Question

6. A man sold his camera for rupees 765 and lost 10%. The amount for which he
should sell it to gain 10% is
(a) 880
(b) 940
(c) 935
(d) 965​

Answer 1

Answer:

SP= ₹750

Loss= 10%

CP = 100/100-L% ×SP

= 100/100-10 ×750

= 100/90 ×750

= ₹833.34

Gain= 5%

SP= 100+G%/100 ×CP

= 100+5/100 ×833

=105/100×833

= ₹875

Answer 2

Answer:

Selling price = 765

loss% = 10%

cost price

s.p = (1-loss%) of x

765 = 90/100 of x

850

For finding the s.p, we will use the formula,

s.p = (1+profit%) of c.p

= 110/100 × 850

935

thus the selling price is 935.
