(a) At which store should Mohit and Rohit shop to spend the least amount of money?
(b) Mohit and Rohit bought a pair of jeans from store R, $1$ shirt from store P and another shirt from store Q. If they had Rs. $1000$, how much will be left?

• A. (a)-S, (b)-Rs. $52$
• B. (a)-P, (b)-Rs. $53.30$
• C. (a)-R, (b)-Rs. $53.30$
• D. (a)-Q, (b)-Rs. $65.50$

Answer 1

The correct option is B (a)-P, (b)-Rs. $53.30$

$\Rightarrow$ $Part\left(a\right)$

$\Rightarrow$ Cost of a pair of jeans and 2 shirts From store $P$

$\Rightarrow$ $Rs.(399.70+2\times 222.40)=844.50$

From store $Q$

$\Rightarrow$ $Rs.(449.90+2\times 224.80)=Rs.899.50$

From store $R$

$\Rightarrow$ $Rs.(499.50+2\times 204.60)=Rs.908.70$

$\therefore$ Mohit and Rohit should stop from store $P$ to spend least amount of money.

$\Rightarrow$ $Part\left(b\right)$

$\Rightarrow$ Cost of a pair jeans from store $R$+ Cost of one shirt from store $P$+ Cost of another shirt from store $Q$

$\Rightarrow$ $Rs.499.50+Rs.222.40+Rs.224.80=Rs.946.70.$

$\therefore$ $Moneyleft=Rs.(1000-946.7)=Rs.53.30.$
