Answer 1

Ashok spends 20% of his salary on rent. so he has 80% of his salary left

he spends two-thirds of the remaining balance, he is then left with Rs. 320 as balance

write an equation to find his salary

x= his salary

x*80/100*2/3 = 320

x*0.8*2/3 = 320

8x/15 = 320

we solve:

8x=320*15

8x=4800

x= 600

his salary: 600Rs
