Answer 1

Let the number of 10 paise coins be x

• Number of 25 paise coins = 2 x

Rs 3.50 = 350 paise and Rs 15.50 = 1550 paise

• 10 x + 25 ( 2 x ) + 350 = 1550

• 10 x + 50 x = 1550 - 350

• 60 x = 1200

• x = $\frac{1200}{60}$

= x = 20

Number of 10 paise coin = 20,

Number of 25 paise coin = 2 x = 2 ( 20 )

$\: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: = 40$

$And \: number \: of \: 50 \: paise \: coins = \frac{350}{50}$

$\: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: = 7$
