Question
The ratio of the pocket money of two persons ‘P’ and
‘Q’ is 5:2, respectively. ‘P’ spends 60% of his pocket money while ‘Q’ spends 25% of his pocket money. If the savings of ‘P’ is Rs. 150 more than that of ‘Q’, then find the total pocket money of ‘P’.Solution
Let the pocket money of ‘P’ and ‘Q’ be Rs. 5x and Rs. 2x respectively
(0.4 × 5x) – (0.75 × 2x) = 150
2x – 1.5x = 150 → 0.5x = 150 → x = 300
Therefore, pocket money of ‘P’ = 5x = Rs. 1500
