Question

Rohanpreet obtained 548 marks out of 800 and Rahman obtained 460 marks out of 600 in Mathematics.Whose performance is better?

Answer 1

Rohanpreet obtained $=\frac{548}{800}=\frac{137}{200}$

Rahman obtained $=\frac{460}{600}=\frac{23}{30}$

L.C.M$(30,200)=600$

$\frac{137}{200}=\frac{137\times 3}{200\times 3}=\frac{411}{600}$

$\frac{23}{30}=\frac{23\times 20}{30\times 20}=\frac{460}{600}$

$\frac{460}{600}>\frac{411}{600}$

$\therefore$ Rahman's performance is better than Rohanpreet.
