Question

in a bag. the number of one rupee coins is three times the number of two rupee coins. If the coins are worth 120 in total, find the number of one rupee coins. by buis hus one-fourth​

Answer 1

$\large\underline{\sf{Solution-}}$

Given that,

Number of one rupee coins is three times the number of two rupee coins.

So, Let assume that

Number of rupee two coins be x

So,

Number of one rupee coins be 3x

Now,

Value of one rupee coin = 1 × 3x = 3x

and

Value of two rupee coin = 2 × x = 2x

According to statement

The total worth of coins = 120

$\rm\implies \:3x + 2x = 120$

$\rm\implies \:\rm \: 5x = 120$

$\rm\implies \:x = 24$

Thus,

Number of rupee two coins is 24

Number of one rupee coins is 72

Hence,

Number of one rupee coins is 72.

VERIFICATION

Number of rupee two coins = 24

Number of one rupee coins = 72

So,

Total value of rupee two coin = 2 × 24 = 48

Total value of one rupee coin = 1 × 72 = 72

Total worth = 48 + 72 = 120

Hence, Verified

Answer 2

QUESTION,

In a bag. the number of one rupee coins is three times the number of two rupee coins. If the coins are worth 120 in total, find the number of one rupee coins. by buis hus one-fourth

SOLUTION,

TO fIND

• The number of one rupee coins. by buis hus one-fourth

GIVEN

• Let the rupee to coin be x

• Number of one rupee coins be 3x

• Value of one rupee coin

= 1 × 3x = 3x

• Value of 2 rupees coin

= 2 × x = 2x

Now,

The total worth of coins = 120

= 3x + 2x = 120

= 5x = 120

x= 120/5

x= 24

• Thus number of rupee two points is 24

• Number of one rupee coins is 72

So,

= Total value of rupee to coins

= 2 × 24 = 48

Total value of 1 rupee coin

= 1 × 72 = 72

Total worth

= 48 + 72

= 120
