Question
The ratio of sugar to flour packets in a store is 6:7. If
18 more packets of each are stocked, the ratio becomes 4:5. Find the original number of flour packets.Solution
ATQ,
Let the number of sugar and flour packets be 6x and 7x.
ATQ:
(6x + 18)/(7x + 18) = 4/5
⇒ 5(6x + 18) = 4(7x + 18)
⇒ 30x + 90 = 28x + 72
⇒ 2x = 18
⇒ x = 9
Original flour packets = 7 × 9 = 63
