View answer & explanation

Correct answer

Answer: (c)C.

3300 m

Why this answer is correct

Common Solution:

Factory 'W',

Total quantity of fabric manufactured = 4500 m

Quantity of Silk fabric manufactured = (8/15) × 4500 = 2400 m

Quantity of Cotton fabric manufactured = (7/15) × 4500 = 2100 m

Factory 'X',

Total quantity of fabric manufactured = 2100 m

Quantity of Silk fabric manufactured = (3/7) × 2100 = 900 m

Quantity of Cotton fabric manufactured = (4/7) × 2100 = 1200 m

Ravi received an amount of ₹11236 by depositing a sum of ₹10000 for 2 years in a bank which provides R% rate of interest compounded annually. What is the simple interest earned on ₹15000 at (R + 3)% rate of interest after (R + 5) years?

  1. AOption (a)

    ₹14500

  2. BOption (b)

    ₹14850

  3. COption (c)

    ₹15200

  4. DOption (d)

    ₹15600

  5. EOption (e)

    ₹14000

View answer & explanation

Correct answer

Answer: (b)B.

₹14850

Why this answer is correct

ATQ,

11236 = 10000(1 + R/100)²

Or, (1 + R/100)² = 11236/10000

Or, (1 + R/100)² = 1.1236

Or, 1 + (R/100) = 1.06

So, R = 6

Now,

P = 15000

R = (6 + 3)% = 9%

T = (6 + 5) = 11 years

SI = (15000 × 9 × 11)/100 = ₹14850

Question 403

SBI Probationary Officer (PO) 2025• Quantitative Aptitude• Quantitative Aptitude

A box contains 7 white balls and 13 red balls. The average weight of the white balls is 9 grams, and the average weight of the red balls is 28 grams. Two white balls weighing X grams and Y grams are removed from the box, and three new red balls with an average weight of (Y - 2) grams are added. The new average weight of all the balls in the box becomes 20 grams. Here, X and Y are two distinct positive integers. Find the average weight of white balls that were removed from the box, if only Y is a prime number, and 20 > X > Y.

  3. COption (c)

  4. DOption (d)

    12 gm

  5. EOption (e)

    None of these

View answer & explanation

Correct answer

Answer: (c)C.

11 gm

Why this answer is correct

Total initial weight White balls = 7 × 9 = 63

Total initial weight Red balls = 13 × 28 = 364

Total initial weight Total balls = 427

Removed white balls = X and Y

Remaining white weight = 63 - X - Y

Remaining white count = 5

Added red balls = 3

Average weight of added red balls = (Y - 2)

Added red weight = 3(Y - 2) = 3Y - 6

Final total weight = (63 - X - Y) + (364 + 3Y - 6) = 421 - X + 2Y

Final number of balls = 5 + 13 + 3 = 21

Final average = 20

Total final weight = 21 × 20 = 420

ATQ,

421 - X + 2Y = 420

Or, −X + 2Y = -1

Or, X = 2Y + 1

Condition:

Y is prime, 20 > X > Y

Case (I): Y = 3

X = 2(3) + 1 = 7

X = 7 (prime)

Not valid

Case (II): Y = 5

X = 2(5) + 1 = 11

X = 11 (prime)

Not valid

Case (III): Y = 7

X = 2(7) + 1 = 15

20 > 15 > 7

Valid

Average weight of removed white balls = (X + Y) ÷ 2

= (15 + 7) ÷ 2 = 22 ÷ 2 = 11 gm

View answer & explanation

Correct answer

Answer: (b)B.

372

Why this answer is correct

Common Solutions:

Let the total number of students who participate in drama from class VIII and class X be 5x and 6x respectively.

The total number of students who participate in dancing from class VIII = 5x - 50

The total number of students who participate in singing from class VIII = 5x - 75

ATQ,

(5x - 50) + (5x - 75) + 5x = 865

Or, 15x - 125 = 865

Or, 15x = 990

So, x = 66

The total number of students who participate in drama from class VIII = 5 × 66 = 330

The total number of students who participate in dancing from class VIII = 330 - 50 = 280

The total number of students who participate in singing from class VIII = 330 - 75 = 255

The total number of students who participate in drama from class X = 6 × 66 = 396

The total number of students who participate in drama from class IX = 1086 - (330 + 396) = 360

The total number of students who participate in dancing from class X = (7/6) × 360 = 420

The total number of students who participate in singing from class X = 125% of 280 = 350

The total number of students who participate in dancing and singing together from class IX = 360 × 2 = 720

The total number of students who participate in dancing from class IX = (100/120) × 528 = 440

The total number of students who participate in singing from class IX = 528 - 440 = 352

Correct answer

Answer: (c)C.

13.14%

Why this answer is correct

Common Solutions:

Let the total number of students who participate in drama from class VIII and class X be 5x and 6x respectively.

The total number of students who participate in dancing from class VIII = 5x - 50

The total number of students who participate in singing from class VIII = 5x - 75

ATQ,

(5x - 50) + (5x - 75) + 5x = 865

Or, 15x - 125 = 865

Or, 15x = 990

So, x = 66

The total number of students who participate in drama from class VIII = 5 × 66 = 330

The total number of students who participate in dancing from class VIII = 330 - 50 = 280

The total number of students who participate in singing from class VIII = 330 - 75 = 255

The total number of students who participate in drama from class X = 6 × 66 = 396

The total number of students who participate in drama from class IX = 1086 - (330 + 396) = 360

The total number of students who participate in dancing from class X = (7/6) × 360 = 420

The total number of students who participate in singing from class X = 125% of 280 = 350

The total number of students who participate in dancing and singing together from class IX = 360 × 2 = 720

The total number of students who participate in dancing from class IX = (100/120) × 528 = 440

The total number of students who participate in singing from class IX = 528 - 440 = 352

Let the initial quantity of Milk and Water be '5x' and '3x' respectively,

Quantity of Milk removed = 32 X (5/8) = 20 Liters

Quantity of Water removed = 32 X (3/8) = 12 Liters

Remaining quantity of milk = (5x - 20) Liters

Remaining quantity of water = (3x - 12) Liters

After adding 12 Liters of water,

Remaining quantity of water = (3x - 12 + 12) = 3x Liters

ATQ,

(5x – 20)/3x = 3/2

Or, 2(5x – 20) = 9x

Or, 10x – 40 = 9x

Or, x = 40

Initial mixture = 8 x 40 = 320 L

  5. EOption (e)

    Rs. 11250 

View answer & explanation

Correct answer

Answer: (a)A.

Rs. 9975

Why this answer is correct

Let number of Rs. 5 coins be 'm'

So, the number of Rs. 2 coins = m + 250

Number of Rs. 0.5 coins = 11m

ATQ,

m + (m + 250) + 11m = 2200

Or, 13m + 250 = 2200

Or, 13m = 1950

So, m = 150

Number of Rs. 5 coins = 150

Number of Rs. 2 coins = 400

Number of Rs. 0.5 coins = 1650

Share of 'R' = 150 × 5 + 400 × 2 + 1650 × 0.5 = 750 + 800 + 825 = 2375

Share of 'P' = (6/5) × 2375 = 2850

Here, (a + 1)/a = 6/5

Or, 5a + 5 = 6a

So, a = 5

Share of 'Q' = (2a/a) × R's share = 2 × 2375 = 4750

ATQ,

Total amount (X) = P's share + Q's share + R's share = 2850 + 4750 + 2375 = 9975

    x < y

  2. BOption (b)

    x > y

  3. COption (c)

    x ≤ y

  4. DOption (d)

    x ≥ y

  5. EOption (e)

    x = y or the relation between x and y can't be established.

View answer & explanation

Correct answer

Answer: (a)A.

x < y

Why this answer is correct

Given:

I. x2 + 36x + 324 = 0

II. y2 – 4y – 221 = 0

Calculation:

I. x2 + 36x + 324 = 0

⇒ x2 + 18x + 18x + 324 = 0

⇒ x(x + 18) +  18(x + 18)= 0

⇒ (x + 18)(x + 18) = 0

⇒ x = (-18), (-18)

II. y2 – 4y – 221 = 0

⇒ y2 – 17y + 13y – 221 = 0

⇒ y(y – 17) + 13(y – 17) =0

⇒ (y – 17)(y + 13) = 0

⇒ y = 17, (-13)

Value of ‘x’RelationValue of ‘y’
-18<17
-18<-13

When we compared the values of ‘x’ and ‘y’ in the table above, we found that there is only ONE relation between X and Y i.e. <. So, a relation between x and y is “x < y”.

∴ After comparison, all the values of x and y the relation is "x < y".

  5. EOption (e)

    x = y or relation between x and y can not be established.

View answer & explanation

Correct answer

Answer: (a)A.

x > y

Why this answer is correct

Given:

I. x2 – 24x + 143 = 0

II. 6y2 – 25y + 26 = 0

Calculation:

From I,

x2 – 24x + 143 = 0

⇒ x2 – 13x - 11x + 143 = 0

⇒ x(x - 13) - 11(x - 13) = 0

⇒ (x - 13)(x - 11) = 0

Taking,

⇒ (x - 13) = 0 or  (x - 11) = 0

⇒ x = 13 or 11

From II,

6y2 – 25y + 26 = 0

⇒ 6y2 – 13y - 12y + 26 = 0

⇒ y(6y - 13) - 2(6y - 13) = 0

⇒ (6y - 13)(y - 2) = 0

Taking,

⇒ (y - 2) = 0 or (6y - 13) = 0

⇒ y = 2 or (13/6)

Comparison between x and y (via Tabulation):

Value of xValue of yRelation
132x > y
1313/6x > y
112x > y
1113/6x > y

 

∴ x > y.

I. x2 + 11x + 18 = 0

II. y2 + 2y + 1 = 0

Calculation:

I. x2 + 11x + 18 = 0

⇒ x2 + 9x + 2x + 18 = 0

⇒ x(x + 9) + 2(x + 9)= 0

⇒ (x + 9)(x + 2) = 0

⇒ x = (-9), (-2)

II. y2 + 2y + 1 = 0

⇒ y2 + y + y + 1 = 0
