Question
Arvind sold 40% more apples than Vishnu. Ratio of number
of apples sold by Vishnu to number of apples sold by Bishwa is 4:7. Find the number of apples sold by Arvind if number of apples sold by Bishwa is 630.Solution
ATQ, Let, number of apples sold by Vishnu and number of apples sold by Bishwa be ‘4x’ and ‘7x’, respectively. So, 7x = 630 Or, x = 90 Number of apples sold by Vishnu = 4x = 4 × 90 = 360 Therefore, number of apples sold by Arvind = 140% of 360 = 504
