Question

A + B = 60
A - B = 40
A / B = ?

Answer 1

Answer:

Given A+B=60 ---(1)

A-B=40 => A=40+B ----(2)

Substitute equation (2) in equation (1),we get

40+B+B = 60

=> 2B+40=60

=> 2B = 60-40

=> 2B = 20

=> B = 20/2

=> B = 10 ----(3)

Substitute B=10 in equation (2),

we get

A= 40+10

=> A = 50 ----(4)

Therefore,



/* from (3)& (4) */

After cancellation,we get



Therefore,
