Answer: (4)
Solution: (4)
C.P. of $40 kg$ of mixture $= \text{₹} [(25 \times 32)+(15 \times 36)]$
$= \text{₹} (800+540)= \text{₹} 1340$
S.P. of $40 kg$ of mixture $= \text{₹} (40 \times 40.2)= \text{₹} 1608$
Profit $= \text{₹} (1608-1340)= \text{₹} 268$
Profit $\%=\frac{268}{1340} \times 100=20 \%$
