Answer 2

Given :

Selling price of each calculator : $198

Gain percent of first calculator : 10%

Loss percent of second calculator : 10%

To find :

The cost price of each calculator.

Solution :

Cost price of first calculator :

$\sf \dashrightarrow \dfrac{100}{(100 + Gain\%)} \times SP$

$\sf \dashrightarrow \dfrac{100}{(100 + 10)} \times 198$

$\sf \dashrightarrow \dfrac{100}{110} \times 198$

$\sf \dashrightarrow \dfrac{10}{11} \times 198$

$\sf \dashrightarrow \dfrac{10 \times 198}{11} = \dfrac{1980}{11}$

$\sf \dashrightarrow \cancel \dfrac{1980}{11} = 180$

Now, we can find the cost price of second calculator.

Cost price pf second calculator :

$\sf \dashrightarrow \dfrac{100}{(100 - Loss\%)} \times SP$

$\sf \dashrightarrow \dfrac{100}{(100 - 10)} \times 198$

$\sf \dashrightarrow \dfrac{100}{90} \times 198$

$\sf \dashrightarrow \dfrac{10}{9} \times 198$

$\sf \dashrightarrow \dfrac{10 \times 198}{9} = \dfrac{1980}{9}$

$\sf \dashrightarrow \cancel \dfrac{1980}{9} = 220$

Hence, the cost prices of first and second calculator is $180 and $220 respectively.
