163) What per cent of selling price would be 34% of cost price if gross profit is 26% of the selling price ?
Correct Answer - Option
(C)
Explanation :
Let the selling price of the article = Rs. 100
∴ Profit = Rs. 26
∴ Cost price of the article = 100 - 26 = Rs. 74
∴ Required % = (34 x 74)/100 = 25.16%
∴ Profit = Rs. 26
∴ Cost price of the article = 100 - 26 = Rs. 74
∴ Required % = (34 x 74)/100 = 25.16%
164) Alok bought 25 kg of rice at the rate of Rs. 6.00 per kg and 35 kg of rice at the rate of Rs. 7.00 per kg. He mixed the two and sold the mixture at the rate of Rs. 6.75 per kg . What was his gain or loss in this transaction ?
Correct Answer - Option
(D)
Explanation :
C.P. of 60 kg mix = Rs. (25 x 6 + 35 x 7) = Rs. 395
S.P. of 60 kg mix = Rs. (60 x 6.75) = Rs. 405
Gain = Rs. (405 - 395) = Rs. 10
S.P. of 60 kg mix = Rs. (60 x 6.75) = Rs. 405
Gain = Rs. (405 - 395) = Rs. 10
165) A discount series of 10%, 20% and 40% is equal to single discount of ?
Correct Answer - Option
(B)
Explanation :
Let original price = Rs. 100
Price after 1 st discount = Rs. 90
Price after 2 nd discount = Rs. (80/100) x 90 = Rs. 72
Price after 3 rd discount = Rs. (60/100) x 72 = Rs. 43.20
∴ Single equivalent discount = (100 - 43.20) = 56.8%
Price after 1 st discount = Rs. 90
Price after 2 nd discount = Rs. (80/100) x 90 = Rs. 72
Price after 3 rd discount = Rs. (60/100) x 72 = Rs. 43.20
∴ Single equivalent discount = (100 - 43.20) = 56.8%
