Question

A person expends 1/6of his income as pocket money and 4/5 portion of the rest for other purposes.If the person saves Rs.100 in a month. Find his monthly income.​

Answer 1

Answer:

600

Step-by-step explanation:

take his total income as x

so , x= x/6(expend in pocket money)+(4/5) of (5/6)(rest for other purposes)*x+100(savings)

x=x/6+(2/3)*x + 100

x/6=100

x=600

Answer 2

Answer:

monthly income =600

expends = 600×1/6=100

(600-100)=500

0ther exp=500×4/5=400

save=(500-400)=100
