"Gain of 5.5 %",
"Loss of 12.5 %",
"Loss of 10 %",
"Loss of 5.5 %"
] | B | Explanation:
Let C.P. of each apple be Re 1/-.
Therefore,
C.P. of 40 apples = Rs. 40
S.P. of 40 apples = Rs. 35
C.P. of 40 apples > S.P. of 40 apples
Loss = 40 – 35 = Rs. 5
Loss% = Loss/c.p. ×100
Loss% = 5/40 ×100

Question seems a bit tricky, but it is very simple.
Just calculate all Cost price, then get 150% of CP.
C.P. = 13000 + 5000 + 1000 = 19000
150% of 19000 = 150/100 * 19000 = 28500
