A boy buys 9 apples for Rs 9.60 and sells them at 11 for Rs 12. Find his gain orloss percent.

Answer:

We know that the cost price of 9 apples = Rs 9.60

Cost price of 1 apple = Rs 9.60/9

Selling price of 11 apple = Rs 12

Selling price of 1 apple = Rs 12/11

By using the formula,

Gain = selling price – cost price

= 12/11 – 9.60/9

= (108-105.60)/99

= Rs 2.40/99

By using the formula,

Gain % = (gain/cost price) × 100

= ((2.40/99)/(9.60/9)) × 100

= 25/11

= 2 3/11%

"hello students i am rita your math
leader tutor
and the today's question is a boy buys
nine apples for rupees 9.60
and seals them at 11 for rupees 12.
find his gain or loss person
in this question it is given that cp
of cp
of 9 apples
is equal to rupees 9.60
so we can find cp of 1 apple
cp off
one apple
is equal to rupees 9.60 divided by
9 so when we divide 9.60
divided by 9 we got 1.06
and in the question it is given sp of
11 apples
sp of
11 apples
is equal to rupees 12
now the sp of
one apple
is equal to rupees 12
by 11 then it becomes
12 divided by 11 we got rupees
1.09 so it means
sp is greater than cp so it is a case of
k so gain is equal to
sp minus c so
1.09 minus
1.06
1.09
minus 1.06
so we got 0.03
and we have to find the percent also and
we know
gain percent is equal to gain
divided by cp into
100 so the gain is 0.03
divided by cp cp
is 1.06 into 100
so 3 by 106
into 100
when we solve this we got 300 divided by
106. we got 2.8
percent
2.8 percent so this is our answer
