Question

An Electrician sells a geyser for rupees 3220 gaining 1/6 of its cost price find the gain percent

Answer 1

Step-by-step explanation:

Cost of geyser=3220

Gain in the cost of geyser=1/6

Gain%=(gain*100/CP)

=536.66*100/3220

=53666/3220

=26833/3220

=16.66%

Answer 2

Gain is $16\dfrac{2}{3}$%.

Step-by-step explanation:

Let, cost price be x

Then gain = $\dfrac{x}{6}$

So, selling price = x + $\dfrac{x}{6}$ = $\dfrac{7x}{6}$

Given, selling price = Rs. 3220

⇒ $\dfrac{7x}{6}$ = 3220

⇒ x = 3220 ÷ $\dfrac{7}{6}$

• We have transposed $\dfrac{7}{6}$ to the right hand side.

⇒ x = 3220 × $\dfrac{6}{7}$

⇒ x = 2760

So, cost price = Rs. 2760

Now, gain = Rs. $\dfrac{2760}{6}$ = Rs. 460

Hence, gain percentage

= $\dfrac{460}{2760}$ × 100%

= $16\dfrac{2}{3}$ %
