Answer 2

Given :

• Twice as many 20 Rupee Notes as 50 Rupee Notes

• Total Amount = ₹ 2700

To find :

• How many ₹ 50 Notes does she have ?

According to the question :

Let No. of. ₹ 50 Notes be ' x '

No. of. ₹ 20 Notes will be = 2x

➳ Total amount = ( No. of. ₹ 50 × 50 ) + ( No. of. ₹ 20 × 20 )

⟹ ( x × 50 ) + ( 2x × 20 )

⟹ 50x + 40x

⟹ 90x

Now,

➳ 90x = Total Amount

⟹ 90x = ₹ 2700

⟹ x = 2700 / 90

⟹ x = 30

∴ There are 30 ₹ 50 Notes.
