The ratio between the amount A and B have before shopping is 10 : 13. After shopping for same amount, the ratio between the amount left for A and B is 2 : 5. The total amount left with A and B after shopping is Rs. 350. Find the amount spent by A on shopping.1. Rs. 3002. Rs. 4003. Rs. 2504. Rs. 7805. Rs. 350

Answer» Correct Answer - Option 2 : Rs. 400

Given:

Let initial amount A and B have before shopping be Rs. 10a and Rs. 13a respectively.

Calculation:

The amount left with A after shopping = 350 × 2/7 = Rs. 100

The amount left with B after shopping = 350 - 100 = Rs. 250

Let amount spent on shopping by A and B each be Rs. m 

⇒ 10a - 100 = m

⇒ 13a - 250 = m

Then,

⇒ 10a - 100 = 13a - 250

⇒ a = 50

∴ The amount spent by A on shopping = 500 - 100 = Rs. 400
