Question
The ratio of the pocket money of two persons ‘C’ and
‘D’ is 4:3, respectively. ‘C’ spends 50% of his pocket money while ‘D’ spends 75% of his pocket money. If the savings of ‘C’ is Rs. 120 more than that of ‘D’, then find the total pocket money of ‘C’.Solution
Let the pocket money of ‘C’ and ‘D’ be Rs. 4x and Rs. 3x respectively
(0.5 × 4x) – (0.25 × 3x) = 120
2x – 0.75x = 120 → 1.25x = 120 → x = 96
Therefore, pocket money of ‘C’ = 4x = Rs. 384
