Question
Ravi has 98 marbles of two colours – green and yellow. If
he bought 28 more yellow marbles, the ratio of green to yellow marbles would become 3:4. Find how many yellow marbles Ravi originally had.Solution
ATQ,
Let the number of green and yellow marbles after buying 28 more be ‘3x’ and ‘4x’ respectively.
ATQ:
3x + 4x = 98 + 28
7x = 126
x = 18
Number of yellow marbles after buying = 4x = 4 × 18 = 72
Number of yellow marbles Ravi originally had = 72 - 28 = 44
