Question

A person usually spent Rs. 48 to buy groundnuts

for roasting and resale. On one occasion he could

buy 1.5 kg of groundnut less for Rs 48 as the price

had gone up by 25%. What was the earlier price of

groundnut per kg?​

Answer 1

1ST Solution :-

suppose, the price of 1 kg groundnut is rs X. And, the person bought y kg in 48 rs.

So, X × y=48

After the increased price,

The price of ground nut per kg= 1.25 X rs/kg

And, he bought (y-1.5) kg

So, 1.25X × (y-1.5)= 48

after solving both equations

we get, X= earlier price of groundnut/kg = 6.40 rs

IF THIS IS DIFFICULT FOR YOU

2ND Solution :-

25%===1/4

4-----5

5------4

1---1.5

5----7.5

48/7.5===6.40 Rs
