Question

A purse contains 10800 in terms of 50 paise 2 rupees and 5 rupees coins in the ratio 2:3:4 find the number of each type of coins

Answer 1

Step-by-step explanation:

50 paise 2 rupees and 5 rupees coins are in the ratio 2:3:4

let number of 50 paise (1/2 rupees) coins = 2n, 2 rupees = 3n and 5 rupees = 4n

given,

2n×(1/2) + 3n×2 + 4n×5 = 10800

=> n + 6n + 20n = 10800

=> 27n = 10800

=> n = 10800/27 = 400

number of 50 paise (1/2 rupees) coins = 2n = 2×400 = 800

number of 2 rupees = 3n = 3×400 = 1200

and 5 rupees = 4n = 4×400 = 1600
