Given, Total number of employees in an organization = 214 employees.

Number of employees participated in clay modelling = 120

Number of employees participated in poster making = 130

Number of employees participated in both clay modelling and poster making = 36

So, Number of employees participated in clay modelling only = Number of employees participated in clay modelling - Number of employees participated in both clay modelling and poster making

So, Number of employees participated in clay modelling only = 120 - 36

So, Number of employees participated in clay modelling only = 84

Similarly,

Number of employees participated in poster making only = Number of employees participated in poster making - Number of employees participated in both clay modelling and poster making

Number of employees participated in poster making only = 130 - 36

∴ Number of employees participated in poster making only = 94

Total employees = Number of employees participated in clay modelling only + Number of employees participated in poster making only + Number of employees participated in both clay modelling and poster making 

Total employees = 84 + 94 + 36

Total employees = 214 employees.

∴ Here, Number of employees participated in poster making only is '94'.

Hence, the correct answer is "94".

The logic followed here is :-

Given equation : 90 D (2 B 5) A 4 B (12 A 10) C 4 B (17 C 10)

After replacing the symbols instead of alphabets in given equation is as follows : 90 ÷ (2 × 5) + 4 × (12 + 10) - 4 × (17 - 10)

= 90 ÷ (2 × 5) + 4 × (12 + 10) - 4 × (17 - 10)

= 90 ÷ 10 + 4 × 22 - 4 × 7

= 9 + 4 × 22 - 4 × 7

= 9 + 88 - 28

= 97 - 28

⇒ (236 × 5 − 8 × 7) / 105

⇒ (1180 − 56) / 105

⇒ 1124/105

∴ The answer = 1124/105

Given:

Distance = 330 km

By driving at the speed of 60 km/h, the driver reaches late by 30 mins

Formula Used: 

Speed = Distance/ Time

Calculation:

Time taken to drive 330 km = 330 km ÷ 60 = 5 hrs 30 min

Appropriate time to reach the destination

⇒ 5 hrs 30 min - 30 min = 5 hrs

Required speed = 330 ÷ 5 = 66 km/h

Difference in speed = 66 - 60 = 6 km/h

⇒ Difference % = $6\over60$ × 100 = 10%

∴ The increase in speed should be 10%.

Given:

Height of boy = 7 feet

Length of the shadow of the boy = 21 feet

Length of the shadow of the man = 15 feet

Concept Used:

The angle of inclination of the light source is constant in both the cases. Hence, the length of shadows vis-a-vis the object length would be proportional in both cases. 

Formula Used:

$B\over S_B$ = $M\over S_M$

Where, B and M are the heights of boy and man respectively

S_B and S_M are the lengths of the shadows of boy and man

Calculation:

According to the question-

⇒ $7\over 21$ = $M\over 15$

∴ M = $15 \times 7\over 21$ = 5 ft

∴ The man is 5 ft tall.

(Formula Used:

1. SI = $P × R× T\over100$

For CI

2. A = P × (1 + $R\over 100$)T

3. CI = A - P

Where, P = Principal, R = Rate, T = Time, A = Amount

4. Effective rate = r1 + r2 + $r_1 × r_2 \over 100$

Where “r1” and “r2” are rates of interest during successive years

Concept Used:

SI and CI for the first year is the same. The difference in the CI and SI for 2 years is due to the compounding part of the interest for the first year.

Calculation:

According to the question

SI for 2 years = ₹ 1,080

⇒ SI for 1 year = ₹ 1,080 ÷ 2 = ₹ 540

Difference between CI and SI for 2 years

⇒ ₹1,128.6 -  ₹1,080 =  ₹48.6

Using SI formula

⇒ R = $48.6× 100\over540× 1$ = 9%

Calculating principal using the SI formula

⇒ P = $1080× 100\over9× 2$ = ₹ 6000

Effective compound interest rate for 2 years

⇒ 9 + 9 +$9 × 9\over100$ = 18.81%

Effective compound interest rate for 3 years

⇒ 18.81 + 9 + $18.81 × 9\over100$ = 27.81 + 1.6929 = 29.5029%

Effective simple interest rate for 3 years = 3 × 9 = 27%

Since the difference in the interest would be due to the difference in the rate component

⇒ Difference in the interest rate = 29.5029% - 27% = 2.5029%

⇒ Difference in the interest at 2.5029% = $6000× 2.5029× 1\over100$ = ₹150.174

∴ The difference in the interest is ₹ 150.174.

Alternate Method Formula Used:

For 2 years, CI - SI = P × (R/100)²

For 3 years, CI - SI = P × (R/100)² × (300 + R)/100

Calculation:

SI for 2 years = ₹ 1,080

⇒ SI for 1 year = ₹ 1,080 ÷ 2 = ₹ 540

Difference between CI and SI for 2 years

⇒ ₹1,128.6 -  ₹1,080 =  ₹48.6

Using SI formula

⇒ R = $48.6× 100\over540× 1$ = 9%

Calculating principal using the SI formula

⇒ P = $1080× 100\over9× 2$ = ₹ 6000

Now, according to the formula for 3 years

CI - SI = 6000 × (9/100)² × (300 + 9)/100

⇒ CI - SI = 6000 × (81/10000) × 309/100

⇒ CI - SI = 150.174

∴ The correct answer is option 3

Given:

SI = ₹5,427

Rate = 9% p.a.

Time = 6 years

Formula Used:

Where, SI = Simple Interest, P = Principal, R = Rate, T = Time

Calculation:

According to the question

P = $5427 \times 100\over 9 \times 6$ = ₹10,050

∴ The sum was **₹**10,050.

Given:

A can complete $\frac{3}{8}$ of a work in 9 days

B can complete 80% of the work in 16 days

Formula Used:

Total Work = Efficiency × Time

Calculation:

Time required by A to complete the work = $9\over {3\over8}$ = 9 × $8\over3$ = 24 days

Time required by B to complete the work = $16\over {80\over100}$ = 16 × $100\over80$ = 20 days

Let the total work be 120 units (LCM of 24, 20)

Efficiency of A = 120 ÷ 24 = 5 units/day

Efficiency of B = 120 ÷ 20 = 6 units/day

Combined efficiency of A and B = 5 + 6 = 11 units/day

Work done by A and B in 5 days = 11 × 5 = 55 units

Remaining work = 120 - 55 = 65 units or $65\over120$ part of the work

According to the question

$65\over120$ part of the work is done by C in $6 \frac{1}{2}$ days

Time required by C to complete the total work

⇒ ${13\over2}\over {65\over120}$ = $13\over 2$ × $120\over65$ = 12 days

Efficiency of C = 120 ÷ 12 = 10 units/day

Combined efficiency of A and C = 5 + 10 = 15 units/day

Time taken by A and C to complete the work = 120 ÷ 15 = 8 days

∴ A and C would complete the work in 8 days.

Given:

CP = ₹50,000

MP is 20% higher than the CP

Discount = 15%

Formula Used:

1. MP = CP × [(100 + Increase%)/100]

2. SP = MP × [(100 - Discount%)/100]

3. Profit% = [(SP - CP)/CP] × 100

Calculation:

MP = ₹50,000 × (120/100) = ₹60,000

SP = ₹60,000 × (85/100) = ₹51,000

⇒ Profit% = [(51000 - 50000)/50000] × 100 = 2%

∴ The percentage profit is 2%.

Shortcut Trick

Let the CP be ₹100

⇒ MP = 100 × (120/100) = ₹120

SP after discount of 15% = 120 × (85/100) = ₹102

⇒ Profit % = [(102-100)/100] × 100 = 2%

∴ The percentage profit is 2%.

Given:

The difference between the SPs of article sold at a discount of $14 \frac{1}{2} \%$  and $10 \frac{1}{2} \%$ is 48

MP is 25% more than the CP

Formula Used:

SP = MP × [(100 - Discount%)/100]

Calculation:

SP for $14 \frac{1}{2} \%$ discount = MP × (100% - 14.5%) = 85.5% of MP

SP for $10 \frac{1}{2} \%$ discount = MP × (100% - 10.5%) = 89.5% of MP

The difference between the discounts offered

⇒ 89.5% of MP - 85.5% of MP = 4% of MP

According to the question

4% of MP = 48

⇒ MP = 48 × (100/4) = ₹1200

CP when MP is 25 % more = $100\over 125$ × 1200 = ₹960

∴ The CP of the article is **₹**960.

Given:

CP of 60% of the articles = SP of 40% of the articles

Formula Used:

Profit% = [(SP - CP)/CP] × 100

Calculation:

According to the question

⇒ $60\over100$ × CP = $40\over 100$ × SP

⇒ $SP\over CP$ = $60\over40$ 

Profit% = [(60 - 40)/40] × 100 = 50% 

∴ The profit percentage is 50%.

Calculation:

Let the income of B be ₹100

⇒ Income of A = 100 × (125/100) = ₹125

Difference = 125 - 100 = 25

B's income is less than A's income by

⇒ $25\over125$ × 100 = 20%

∴ B's income is less than A's income​ by 20%.

Formula Used:

If a : b :: c : d

Then by 4^th proportional formula

a/b = c/d

Calculation:

According to the question

0.45/x = 3/8

Let the amount with Rohit be a

⇒ Amount with Manoj = (1320 - a)

According to the question

⇒ $10\over21$ × a = $5\over7$ × (1320 - a)

⇒ 10a = 15 × (1320 - a)

⇒ 10a = 19,800 - 15a

⇒ 25a = 19,800

⇒ a = $19,800\over 25$ = ₹792

∴ The amount with Rohit is ₹792.

Calculation:

According to the question

Capacity of Pond = 50 × 25 × 4 = 5000 m3

∴ The capacity of the pond is 5000 m3.

Concept Used:

The greatest number that would leave the same remainder in each case would be the HCF of the difference of the numbers.

Calculation:

Difference of the numbers

⇒ 580 - 265 = 315

⇒ 825 - 580 = 245

⇒ 825 - 265 = 560

Using the factorial method

315 = 3 × 3 × 5 × 7

245 = 5 × 7 × 7 

560 = 2 × 2 × 2 × 2 × 5 × 7

⇒ HCF of 315, 245, and 560 = 5 × 7 = 35

∴ The largest number that divides 265, 580, and 825 and leaves the same remainder in each case is 35.

Given:

By selling an article for ₹340, a trader loses 20%

Formula Used:

$SP_1\over 100-Loss\%$ = $SP_2\over 100+Gain\%$

Calculation:

According to the question

$340\over 100-20$ = $SP_2\over 100+15$

⇒ SP2 = $340\times115\over80$ = Rs 488.75.

∴ The article should be sold at **₹**488.75.

Shortcut Trick

SP at 20% loss is ₹340

⇒ (80/100) CP = ₹340

⇒ CP = ₹[(340 × 100)/80]

SP at 15% profit = $\frac{340×100}{80}$ × $\frac{115}{100}$ = 488.75

∴ The article should be sold at **₹**488.75.
