Question

Kishore has Rs.$p$. Hari has Rs.$3$ more than Kishore and Ashok has Rs.$7$ less than Hari. Altogether the three boys have Rs.$20$. How much money does Kishore have?

• A. Rs.$30$
• B. Rs.$10$
• C. Rs.$7$
• D. Rs.$3$

Answer 1

The correct option is C Rs.$7$

Given : Kishore have Rs $p$

And Hari have Rs $3$ more than Kishore

Then, Hari have $p+3$ Rs

Ashok have Rs $7$ less than Hari

Then, Ashok have $p+3-7$ Rs

But three boys all together have Rs $20$

$\therefore p+(p+3)+(p+3-7)=20$

$\Rightarrow p+p+3+p+3-7=20$

$\Rightarrow p+p+p=20-3-3+7$

$\Rightarrow 3p=21$

$\Rightarrow p=7$
