Explanation

Given Data 

S.P = 220     Gain=10%  C.P=?

We know that :

S.P=[ 100 +Gain]/100 * C.P 

We Have to find C.P, so re-arrange the formula 

⇒ C.P= 100/[ 100 +Gain] * S.P

Putting given data:

⇒ C.P= 100/[ 100 +10] * 220

⇒ C.P=200

Explanation

A man sold two scooters for 24000 each.

Find the cost price of one scooter at gain of 20% :-

C.P = (S.P × 100)/(100 + gain)

= (24000 × 100)/(100 + 20)

= 2400000/120

= 20000

Explanation

The CP of the gun = Rs. 2500

The SP of the gun = Rs. 900

The loss is = CP - SP = Rs. ( 2500 - 900 )

= Rs. 1600

Hence, the loss incurred by Akbar is 64%.

Explanation

Let the S.P. be Rs. 100

Then C.P will be Rs. 25

Profit will be 75

Profit %=  75/25×100%

=300%

Explanation

S.P. = Rs. 475, Loss = 5%

C.P. = 100/100 - 5   x  475  = Rs. 500

In the second case, gain = 5%

S.P. = 100 + 5/100  x  500 = 525

Explanation

Simple mathematics question … (solve for X)

12/22 = 30/X

12X = 22 * 30

12X = 660

X = 55

Explanation

Explanation

20% discount on 28,800 is calculated as:

Discount = 28,800 * 20/100 = 5,760

Price after discount = 28,800 - 5,760 = 23,040

Explanation

Let's say the cost price (CP) of the washing machine is x.

Given that the GST rate is 17%, the selling price (SP) would be:

SP = x + 0.17x

SP = 1.17x

Given that SP = Rs 15,912:

1.17x = 15912

x = 15912 / 1.17

x = 13600

Explanation

Loss = Cost price of 5 balls

Loss = 720 - (Selling price of 17 balls)

Loss = Cost price of 17 balls - Selling price of 17 balls

Cost price of 17 balls = Selling price of 17 balls + Loss

= 720 + (Cost price of 5 balls)

Cost price of 1 ball = 60
