A milkman sold two of his buffaloes for Rs 20,000 each.
On one he made a gain of 5% and on the other a loss of 10%.
Find his overall gain or loss.
Answer:
The overall gain is = Rs 1270
Solution:
S.P. of each buffalo = Rs 20,000
5% gain means a profit of Rs 5 on the C.P. of Rs 100.
If the S.P. is Rs 105, and then C.P. is Rs 100.
If S.P. is Rs 20,000, then C.P. =
× Rs 20,000 = Rs 19048
Gain = Rs (20000 – 19048) = Rs 952
10% loss on the other buffalo means:
If S.P. is 90, then C.P. is Rs 100
So, if S.P. is Rs 20,000, then C.P. =
× Rs 20,000 = Rs 22222
C.P. of the other buffalo = Rs 22222
Loss = Rs (22222 – 20000) = Rs 2222
Overall Loss = Rs (2222 – 952) = Rs 1270
Question 8
The price of a T.V. is Rs. 13,000.
The sales tax charged on it is at the rate of 12%.
Find the amount that Vinod will have to pay if he buys it.
Answer:
Rs. 14560
Solution:
Price of the T.V. = Rs 13,000, Sale tax charge = 12%
Sale tax on the T.V. = 12% of Rs 13,000 = Rs
× 13000 = Rs 1560
Amount paid by Vinod for the T.V.= Rs (13000 + 1560) = Rs 14560.
