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. (Hint: Find CP of each)
Answers
buffalo = Rs 20000 The milkman made a gain of 5% while selling one buffalo. This means if C.P. is Rs 100, then S.P. is Rs 105. C.P. of one buffalo =2000×100/105= Rs 19,047.62 Also, the second buffalo was sold at a loss of 10%. This means if C.P. is Rs 100, then S.P. is Rs 90. ∴C.P. of other buffalo =2000×100/90= Rs 22222.22 Total C.P. = Rs 19047.62 + Rs 22222.22 = Rs 41269.84 Total S.P. = Rs 20000 + Rs 20000 = Rs 40000 Loss = Rs 41269.84 − Rs 40000 = Rs1269.84 Ans,- ,the loss of milkman is, Rs 1,269.84.
selling price of one buffalo is 20,000
gain = 5%
c.p = ?
c.p = s.p × 100 / 100 + profit %
= 20,000 × 100 / 100 + 5
=20,005
A/q
selling price of another buffalo is 20,000
loss = 10%
c.p = ?
c.p= s.p × 100 / 100 _ loss %
= 20,000 × 100 / 100 _ 10
= 19,990
whole c.p= 20,005 + 19,990
= 39995
whole s.p = 20,000 + 20,000
= 40,000
hence,
profit = s.p _ c.p
= 40,000 _ 39,995
= 5
profit % = profit / c.p × 100
= 5 / 39995 × 100
= 1/ 799900
