Question

the difference between 12 times the length and 10 times the length of a line is 120 cm. taking the length of the line to be x, find the length of the line in cm​

Answer 1

Let the length be x cm

12 times the length = 12x cm

10 times the length = 10x cm

Their difference = 120 cm

ATQ, 12x cm - 10x cm = 120 cm

or, 2x = 120

or, x= 120/2

or, x= 60

Ans :- The length is 60cm

Hope it helps
