To find:

Find the number

Solution:

Let the required number be 'a'

5times of a =5×a= 5a

if 4 is added to 5a then it=5a+4.....(1)

7times of a=7×a=7a

if 2 is subtracted from 7a then it =7a-2...(2)

According to the problem (1)&(2) are equal

5a+4=7a-2

=>4+2=7a-5a

=>6=2a

=>2a=6

=>a=6/2

=>a=3

The required number is 3

Answer:

The required number is 3

Check:

LHS=>5(3)+4=15+4=19

RHS=>7(3)-2=21-2=19

LHS=RHS is true for a=3
