Question

Three friends pool in money to buy a birthday gift for a common friend. What fraction of the money pooled in was contributed by the friend who paid the largest part of the money collected? Statements: 1) On Nriend contributed three times the amount contributed by another . II) One friend contributed 30% of the money collected.​

Answer 1

One friend contributed three times the amount contributed by another.

Step-by-step-explanation:

• Let the cost of the gift is x dollars,

• Since, Declan contributes 4 dollars more than 1/4 of the cost of the gift,

• So, Declan's contribution = x/4+4

• Also, Ed contributes 1 dollar less than 1/3 of the cost of the gift,

• So, Ed's contribution = x/3-1

• Again frank contributes the remaining 22 dollars,

• ∵ Only three person contributed,

• Thus, the total price of the cost = x/4+4+x/3-1+22

• =3x+4x/12+25

• =7x/12+25

• =7x/12+25=x

• 7x/12=x-25

• 7x=12x-300

• 300=12x-7x

• 300=5x=x=300/5=60

Hence, the cost of the gift is $ 60.
