Question

1/10 x + 70% x = 5/2

Answer 1

1/10 x + 70% x = 5/2

=>1/10 x + 70/100 x = 5/2

=>1/10 x + 7/10 x = 5/2

=>x.(1/10+7/10)=5/2

=>x.8/10=5/2

=>x.4/5=5/2

=>x=5/2:4/5

=>x=5/2.5/4

=>x=25/8

Answer 2

1/10x + 70% x = 5/2

=> 1/10x + 70/100 x = 5/2.

=> 1/10x + 7/10x = 5/2

=> x.( 1/10 + 7/10 ) = 5/2

=> x . 8/10 = 5/2

=> x . 4/5 = 5/2

=> x = 5/2 : 4/5 

=> x = 5/2 x 5/4

=> x =25/8

Answer 3

1/10x + 70% x = 5/2

=> 1/10x + 70/100 x = 5/2.

=> 1/10x + 7/10x = 5/2

=> x.( 1/10 + 7/10 ) = 5/2

=> x . 8/10 = 5/2

=> x . 4/5 = 5/2

=> x = 5/2 : 4/5 

=> x = 5/2 x 5/4

=> x =25/8
