Explanation

We know that th CP of 1 toffee =₹1/5

SP of 1 toffee = ₹1/2

Since SP is more than CP it's Gain

Gain=SP−CP

=1/2−1/5

=3/10

∴Gain%=(Gain×100)/CP

=((3/10)×100)/(1/5)

=150% 

Explanation

A+B+C=395

B=A+25%(A) (or) C+20%(C)/ 

B=1.25A (or) 1.2C

subs one condition at a time 

2.25A+C=395 ................. eq 1 

A+2.2C=395...................... eq 2 

multiply eq 2 by 2.25 and subtracting with eq 1 

2.25A+C=395

2.25A+4.95C=888.75

−3.95C=−493.75

C=125

B=1.2(C)=1.2(125)=150

A=395−150−125=120

A=120
