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 |
