1.	Suresh and Ramesh together invested Rs 144000 in the ratio 4 : 5 and bought a plot of land. After some years they sold it at a profit of 20%. What is the profit each of them got?
Answer» Total investment = Rs 144000 Profit earned = 20% ∴ Total profit = 20% of 144000 = 20/100 x 144000 = Rs 28800 Proportion of investment of Suresh and Ramesh = 4:5 Let the profit of Suresh be Rs 4x and that of Ramesh be Rs 5x. 4x + 5x = 28800 ∴ 9x = 28800 ∴ x = 28800/9 = 3200 ∴ Suresh’s profit = 4x = 4 × 3200 = Rs 12800 Ramesh’s profit = 5x = 5 × 3200 = Rs 16000 ∴ The profit earned by Suresh and Ramesh are Rs 12800 and Rs 16000 respectively.

Answer»

Total investment = Rs 144000

Profit earned = 20%

∴ Total profit = 20% of 144000

= 20/100 x 144000

= Rs 28800

Proportion of investment of Suresh and Ramesh = 4:5

Let the profit of Suresh be Rs 4x and that of Ramesh be Rs 5x.

4x + 5x = 28800

∴ 9x = 28800

∴ x = 28800/9

= 3200

∴ Suresh’s profit = 4x = 4 × 3200 = Rs 12800

Ramesh’s profit = 5x = 5 × 3200 = Rs 16000

∴ The profit earned by Suresh and Ramesh are Rs 12800 and Rs 16000 respectively.
