Question

a grocer brought 100 kg of rice for 1200 years old half of the Rise Rs 14 per kg at was rate should he sell the rest make profit of 20% on hold the whole?

Answer 1

Given
Total quantity =100kg
Cost price =₹1200 (I think it is one and half)

So 50kg sold at ₹14/kg
Sp of 50kg =50x14=₹700

He wants to make profit of 20%

So Sp must be =1200x120/100=1440

Now he already sold 50kg rice and get 700 rs

Left =50kg
Money to earn =1440-700=740

So 1kg price =740/50=₹14.80



This is ur ans hope it will help you in case of any doubt comment below

Answer 2

C.p of 100 kg rice =. 1200
S.p. of 50 kg rice= 50× 14 = 700
He wants a total profit of 20%
Then
S.p. = P%+ c.p.
= 20/100×1200+ 1200
=1440
S.p. for 100 kg should be 1440
But he sold 50 kg for 14rs./ Kg
Remaining 50 kg should be sold for = 1440-700= 740
S.p. for remaining 50 kg should be sold for 740
S.p. for 1 kg should be = 740/50 = 14.80
