Question

please solve the 7th and 9th question

Answer 1

9. selling price of car=300000
profit=25/100×300000
=75000
so cost price = selling price - profit
= 300000-75000
=225000 is the answer

6. s.p of watch = 1190
loss= 15/100×1190
=178.5
c.p= s.p+loss
=1190+178.5
=1368.5
now if he wanted to gain 5 % profit then selling price should be
c.p+5% of c.p
=1368.5+5/100×1368.5
=1368.4+68.425
=1436.8 (approx.)
and u can find the 7 th question by same method

10. s.p of sari= 2100
profit=16×2/3%
= 50/3 %
c.p = s.p - profit
= 2100-50/3/100×2100
=2100-350
=1750 answer

Answer 2

Question 7:

Find the percentage that the cycle is sold:

100 - 12 = 88%

Find the cost price:

88% = Rs 660

1% = Rs 660 ÷ 88 = Rs 7.5

100% = 7.5 x 100 = Rs 750

Find the price that he needs to sell:

8% gain = 8% x Rs 750 = 0.08 x 750 = Rs 60

Selling Price = Rs 750 + Rs 60 = Rs Rs 810

Answer: He needs to sell it at Rs 810

Question 9:

Find the percentage that the car was sold at:

100 + 25 = 125%

Find the cost price:

125% = Rs 300,000

1% = 300,000 ÷ 125 = Rs 2400

100% = 2400 x 100 = Rs 240,000

Answer: The car was purchased at Rs 240000
