Question

a quantity of tea is sold at rupees 48 per kg at a profit of 20 % the total gain is rupees 90 what is the quantity of tea sold?

Answer 1

Let the quantity sold be x

20% 0f 48x = 90
48x = 90(100/20)
48x= 450
x= 9.375kg
x≈9kg

Answer 2

Gain per kg
= 20 % of 48
= (20/100) × 48
= 48/5

Hence there is gain of Rs. 48/5 per 1 kg
let the gain of 90 Rs be for x kg

48/5 = 90/x
x = (90×5)/48
x = 9.37 kg
