Question

Ronald buys a geyser for $ 3680 and sells it at a gain of 7¹/₂%. For how much does he sell it?​

Answer 1

Answer:

your answer is here !

Step-by-step explanation:

CP of the geyser = $ 3680.

Gain % = 7¹/₂% = 15/2%.

Therefore, SP of the geyser = [{(100 + gain %)/100} × CP]

= $ [{(100 + ¹⁵/₂)/100} × 3680]

= $ {(215/200) × 3680}

= $ 3956

Hence, Ronald sells the geyser for $ 3956.

Answer 2

Answer:

He sells it for $3956

Step-by-step explanation:

Cost Price = CP = $3680

Profit% = 7.5            [Also called as Gain%]

Selling Price = SP = ?

Profit% = 100*(Profit/CP)

Thus,

7.5 = 100*(Profit/3680)

Profit = (3680 * 7.5)/100

          = 276

Profit = SP - CP

276 = SP - 3680

SP = 3680 + 276

     = 3956

The Selling Price is $3956

Check:

Profit = SP - CP = 3956 - 3680 = 276

Profit% = 100*(Profit/CP) = 100*(276/3680) = 27600/3680 = 7.5
