Question 11

A man purchased two fan for ₹ 2160. By selling one fan at  a profit of 15% and the other at a loss of 9%. He neither gain nor losses on the whole transection. Find cost price of each fan.

C.P. of first fan = ₹810
C.P. of second fan = ₹1350
Solution Hint:
Let CP of first fan = x
Profit = 15%

$\bg{green} SP=\left(\frac{100+15%}{100}\right)\times x$   $\bg{green}=\frac{115}{100}x$
C.P. of second fan = 2160 - x
Loss = 9%

$\bg{green}SP=\left(\frac{100-9%}{100}\right)\times(2160-x)$

$\bg{green}=\frac{91}{100}(2160-x)$
As the person have no loss no profit on the whole transection so
Total SP of two fans = CP of two fans

$\bg{green}\frac{115}{100}x+\frac{91}{100}(2160-x)=2160$

115x + 91(2160 - x) = 216000

⇒ x = 810

C.P. of first fan = ₹810
C.P. of second fan = ₹1350

Question 12

Ramesh marked his goods at 40% above the cost price but allows a discount of 5% for cash payment to his customers. What actual profit does he make if he receives ₹1064 after allowing the discount.

Answer : Actual Profit = ₹264
Solution Hint
Let CP = ₹ 100
MP = 100 + 40% of 100 = ₹ 140
Discount = 5%

$\bg{green}SP=\left(\frac{100-5}{100}\right)\times 140=133$
Profit = SP-CP = 133-100 = ₹33
If SP = ₹133 then profit    = ₹ 33
If SP = ₹1 then profit        = ₹ 33/133
If SP = ₹1064 then profit  = ₹ (33/133) 1064
= ₹ 264

Question 13

Question 14

By selling 42 oranges a person loses a sum equal to selling price of 8 Oranges. Find loss %

Answer : Loss 16%
Solution Hint
Let SP of on orange = ₹ 1
SP of 8 oranges       =  ₹ 8
SP of 42 oranges     =  ₹ 42
ATQ
Loss                        = ₹ 8
CP                           = 42 + 8 = ₹ 50

$\bg{green}Loss%=\left(\frac{8}{50}\right)\times 100=16%$

Question 15

A fruit seller bought Bananas at the rate of ₹ 45 per dozen and sold them at the rate of ₹ 45 per 10 bananas. Find gain or loss %

Solution Hint
LCM of 12 and 10  = 60
CP of 12 Bananas   =  ₹ 45
CP of 1 Bananas     =  ₹ 45/12
CP of 60 Bananas   = (45/12)✕ 60 = ₹ 225
SP of 10 Bananas   = ₹ 45
SP of 1 Bananas     = ₹ 45/10
SP of 60 Bananas   = (45/10)✕ 60 = ₹ 270
Profit = 270-225     = ₹ 45

$\bg{green}Profit%=\left(\frac{45}{225}\right)\times 100=20%$
