Rs.395 are divided among A,B andC in such a manner that B gets 25% more than A and 20% more than C. Then A s share is:
- 320
- 120
- 180
- 190
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
