Question

JOY’S PRESENT AGE IS 2 TIMES LOY’S . IF LOY =X AND X=75-2X WHAT WAS JOY’S PRESENT AGE?
​

Answer 1

Loy = x = 75-2x
Joy = 2x

Answer 2

150 - 4X

Given:

Joy's present age is 2 x Loy's present age

Loy's present age = X

Now, X = 75 -2X ------ (i)

Hence, Joy's present age = 2X  --------- (ii)

we have to find Joy's present age.

By equation (i) and (ii)

Joy's present age = 2( 75-2X)

                              = 150 - 4X (where X is the present age of Loy's)

Hence, Joy's present age is 150 - 4X
