A bag contains Rs 11,400 in the form of corrency notes of Rs 100, Rs 50 and Rs 10 in the ratio 3 : 4 : 10. How many notes are there of Rs 50?

• A. 76
• B. 72
• C. 56
• D. 48

Answer 1

The correct option is A 76

Let the number of currency notes of Rs 100 Rs 50 Rs 10 be 3x, 4x and 10x respectively

$\therefore 3x\times 100+4x\times 50+10x\times 10=11400$

$\Rightarrow 300x+200x+100x=11400$

\Rightarrow 600x=11400$

$\Rightarrow x=19$

So 50 rupee note =$4\times 19=76$
