Question

Rohan weight 10kg more than Sameer. their combined weight is 90kg .the weight of Sameer is.......?

Answer 1

let Sameer weight be x
then Rohan weight will be 10+x
therefore,
x+10+x=90
10+2x=90
2x=90-10
2x=80
x=80/2
x=40
hence Sameer weight is x=40kg
Rohan weight=50kg

Answer 2

let's the weight of Sameer​ be x
weight of Rohan = x+10
total weight = x+x+10
= 2x+10 = 90
= 2x=90-10
= 2x=80
= x = 80/2
= x = 40
weight of sammer = 40
weight of Rohan = 50
