Question

In a maths examination, Ramesh scored half the marks as that of Suresh and Suresh scored $\frac{3}{2}$ marks as that of Rakesh. If Ramesh scored $60$ marks out of $150$, how much did Rakesh score?

• A. $30$
• B. $45$
• C. $60$
• D. $80$

Answer 1

The correct option is D $80$

$MarksofRamesh=\frac{MarksofSuresh}{2}$ and

$MarksofRakesh\times \left(\frac{3}{2}\right)=Marks$ $of$ $Suresh$

Now, we know that Marks of ramesh= $\frac{60}{150}$

and Marks of Suresh is double Ramesh's Marks$=\frac{120}{150}$

and Marks Of Rakesh is =$\frac{2}{3}\times \frac{120}{150}$

$\Rightarrow \frac{80}{150}$

Rakesh scored $80$ marks out of $150.$

Therefore Answer is $\left(D\right)$
