AFCAT Model Paper 10

Given:
Vendor mixes 13 kg of millet at Rs.10 per kg with 15 kg of millet of other variety at Rs.18 per kg
Formula Used:
Profit = S.P - C.P
EXPLANATION & CALCULATIONS :
C.P. of 28 kg millet = Rs. ( 13 x 10 + 15 x 18 )
⇒ Rs. ( 130 + 270 ) = Rs. 400.
S.P. of 28 kg millet = Rs. (28 x 15)
⇒ Rs.420.
Profit = S.P. of 28 kg millet - C.P. of 28 kg millet
⇒ 420 – 400 = 20
Profit percentage = (Profit /Cost Price) x 100
⇒(

20

400

)×100
⇒ 5%
