Question

Four friends contribute sums of money to a charitable organization in the ratio of 2 : 4: 5: 7. If the largest amount contributed is $1400. calculate the total amount contributed by the four people.

Answer 1

Answer:

3600

Step-by-step explanation:

7x=1400

x=200

2x+4x+5x+7x=total amount

2×200+4×200+5×200+7×200=total amount

400+800+1000+1400=total amount

3600=total amount

Answer 2

Step-by-step explanation:

let the common ratio be X

therefore they all contribute 2x,4x,5x and 7x

we know largest amount is 7x and is value is given as 1400;

7x=1400

X=200

total contribution=2×200+4×200+5×200+7×200=3600
