Correct Answer - Option 2 : 20
Calculation:
Shirley can buy 50 peaches or 40 kiwis.
Let the price of one peach be Rs. x
The total amount Shirley has = Rs.50x
∴ 40 kiwis cost 50x
∴ one kiwi costs 1.25x
10% of the total amount is retained for taxi fare = 10% of 50x
⇒ 5x
20 kiwis bought for 20 x 1.25x
⇒ 25x
Money left with Shirley = 50x – (Taxi fare) – (kiwis cost)
⇒ 50x – 5x – 25x
⇒ 20x
One Peach was for Rs.x.
∴ 20 peaches can be bought with Rs. 20x
∴ Shirley bought 20 peaches.
