Q .Sami and Mani purchased share worth their basic salaries respectively which are in the ratio of 3 : 4 later on the company gave 50 shares to either or them , due to which the ratio changed to 8 : 9 .If the worth of each share is Rs 100 , what is the basic salary of the person who got less shares?

First Trick-

Let their basic salaries be 3x and 4x

3x + 50 / 4x + 50 = 8 / 9

9(3x + 50) = 8(4x + 50)

27x + 450 = 32x + 400

5x = 50

x = 10

Number of Sami's share , who got less shares =3x = 3 * 10 = 30 shares

Basic salary of Sami = 100 * 30 = Rs. 3000

Second Trick-

SmaiMani

Initial share 34

Final share 89

Difference in ratio 5 = 50 Shares

Difference in ratio 3 = 50 / 5 * 3 = 30 Shares

Basic salary of Sami = 100 * 30 = Rs. 3000
