A) 50%
B) 65%
C) 37.5%
D) 40%
E) None of these
View Answer
Answer: option (C)
Explanation:
Let us assume a packet of rice be 1kg
Actual weight of 80% of 1000gm = 800gm
Let C.P. of each gm be Re. 1. Then, C.P. of this packet = Rs. 800
S.P. of this packet = 110% of C.P. of 1kg = Rs. (110/100*1000)=Rs.1100
∴ Profit% = (300/800*100)%= 37.5%

D) Rs.350
E) None of these
View Answer
Answer: option (B)
Explanation:
S.P. = C.P. + 1/4 C.P. = 5/4 C.P.
∴ 5/4 C.P. = 375 => C.P. = Rs. (375* 4/5)= Rs.300

15. A man bought goods worth Rs. 8000 and sold half of them at a gain of 10%. At what gain percent must he sell the remaining so as to get a gain of 25% on the whole?
A) 55%
B) 20%
C) 35%
D) 40%
E) None of these
View Answer
Answer: option (D)
Explanation:
Let the required profit percent be x%
Then, (110% of 4000) + [(100 + x)% of 4000] = 125% of 8000
(110/100*4000)+ (((100+x))/100*4000)= (125/100)*8000
4400+4000+40x=10000
4000 + 40x = 10000 – 4400
40(100 + x) = 5600
100+x=140
x = 40%
