Question
640 gms mixture contains sugar and rice in the ratio of
3:5 respectively. If 40 gms of sugar and 80 gms of rice are added to the mixture, then calculate the ratio of rice to sugar in the resultant mixture.Solution
Quantity of sugar in the mixture = (3/8) × 640 = 240 gms Quantity of rice in the mixture = 640 - 240 = 400 gms Required ratio = (400 + 80) : (240 + 40) = 12:7
