The of a pencil is 5 R.s. more than the cost of an eraser. If the cost of 8 pencils and 10 erasers is 400, find the cost of each ​

Answer»

ANSWER:

let the COST of each eraser be RUPEES X

therefore, the cost of each PENCIL is (x + 5)

according to the condition,

8(x + 5) + 10x = 400

8x + 40 + 10x = 400

18x = 400 - 40 = 360

x = 360/18

x = 20

thus, the price of each eraser is rupees 20 and the cost of each pencil is rupees 25.
