View answer & explanation

Correct answer

Answer: (a)A.

\(12\frac{1}{2}\) days

Why this answer is correct

Given:

2M + 3B = 10 Days

3M + 2B = 8 Days

Concept:

Find Individual efficiency of each men and boy and using it to find total time taken to complete the same task

Calculation:

Taking L.C.M  of above equations we get total unit of work as 40 Days

Efficiencies,

2M + 3B = 4

3M + 2B = 5

Solving above equations we get 

M = 7/5

B = 2/5

Efficiency of 2M + 1B = 16/5

Conclusion:

So, Time taken = 40/(16/5) = 200/16 =12.5 Days

Question 315

Kolkata Police SI 2018• Full Test

The HCF and LCM of two different numbers both greater than 13, are 13 and 273 respectively. Then the sum of the numbers is:-

  1. AOption (a)

    290

  2. BOption (b)

    288

  3. COption (c)

    286

  4. DOption (d)

    130

View answer & explanation

Correct answer

Answer: (d)D.

130

Why this answer is correct

Let the two numbers be a and b.

Given:

a>13 and b>13

L.C.M = 273

H.C.F = 13

Concept:

Since the H.C.F. is 13, we can write

a = 13x

b = 13y

Calculation:

for any two positive integers x and y.

L.C.M. = 273. We can write

13 × x × y = 273

xy = 21 

13x >13 

⇒ x >1

13y >13

⇒ y >1

We need to find x and y.

So, factors of 21 are 1,3,7 and 21.

(x,y) can't be (1,21) or (21,1) since x and y should be greater than 1.

Therefore, (x,y) = (3,7) or (7,3)

Thus,

a = 13×3 = 39

b = 13×7 = 91

Thus, (a,b) = (39,91) or (91,39)

Sum of a and b = (a+b) = 39+91 = 130

Rs. 175.50

Why this answer is correct

Given:

Final mixture price = Rs.153

Concept:

Assume that the Third Variety of Tea quantity is X.

Calculation: 

(1261+1351+2*x)/(1+1+2)= 153

⇒ 261 + 2x = 4×153

⇒ x = 351/2

⇒ x =175.50

∴ Price of third variety tea is Rs. 175.50
