A sum of RS. 88000 is to be divided among A, B, and C such that for every rupee, A gets, B gets 75 paise and for every rupee, B gets , C gets 90 paise . How much is C’s share

  1. 28345

  2. 24495

  3. 29887

  4. 30500


Correct Option: B

AI Explanation

To find out the share of C, we need to determine the ratio in which the total sum of Rs. 88000 is divided among A, B, and C.

Let the share of A be x, the share of B be y, and the share of C be z.

According to the given conditions:

  • For every rupee that A gets, B gets 75 paise. This can be written as: x:y = 1:0.75 = 4:3
  • For every rupee that B gets, C gets 90 paise. This can be written as: y:z = 1:0.9 = 10:9

We can equate the two ratios to find the relationship between x, y, and z: 4:3 = 10:9

To solve this proportion, we can cross-multiply: 4 * 9 = 3 * 10 36 = 30

This is not true, so the given ratios are not equal.

To find the correct ratios, we can assume a common multiple of 36.

The ratio for A, B, and C can be written as: A:B:C = 4x:3x:3.6x (where x is the common multiple)

The total sum of Rs. 88000 is divided in the ratio 4:3:3.6, which can be added as follows: 4x + 3x + 3.6x = 88000

Simplifying this equation, we get: 10.6x = 88000 x ā‰ˆ 8301.89

Now, we can find the share of C: C's share = 3.6x ā‰ˆ 29887.08

Therefore, C's share is approximately Rs. 29887.

Hence, the correct answer is option C) 29887.

Correct Option: D

A salesman earns a commission of 3% on the value of sale that he makes. If by selling a radio at 60 % of the marked prices, he earns a commission of Rs. 12, then the marked price of the radio is?

  1. 667

  2. 700

  3. 655

  4. 680


Correct Option: A

AI Explanation

To solve this question, let's assume the marked price of the radio is x.

According to the given information, the salesman sells the radio at 60% of the marked price. Therefore, the selling price of the radio is 0.6x.

The salesman earns a commission of 3% on the selling price. This commission is given as Rs. 12.

We can set up the equation:

0.03 * (0.6x) = 12

Simplifying the equation:

0.018x = 12

Dividing both sides by 0.018:

x = 12 / 0.018

x = 666.67

Therefore, the marked price of the radio is approximately Rs. 667.

The correct answer is option A.
