John, Peter and Mary shared a sum of
money in the ratio 2:4:9. John and Peter
together received $360. How much money
in all was shared?
(A) $480
(B) $540
(C) $600
(D) $900

D

Step-by-step explanation:

Here, we want to know the total amount of money shared

Total ratio is 2 + 4 + 9 = 15

Now, John and Peter with ratios 2 and 4 equals $360

If we combine their ratios, what we have would be

6:9

Let the amount shared be x

Now, mathematically

6/15 * x = 360

6x = 15 * 360

x = (15 * 360)/6

x = $900

for this case we have the following expression:

to solve, we rewrite the expression as:

we apply double c and we have:

thus, the quotient is 48.

so, patel found a wrong ratio and the multiplication was incorrect.

option d

1)is not similar since corresponding sides are not in the same ratio

2)are similar since corresponding sides are in the same ratio and corresponding angles are equal

hope it will
