Question

Four positive numbers are in the ration 2 : 3 : 5 : 7. The sum of the two largest numbers is 156. What is the sum of all the numbers

Answer 1

Answer:

221 is the sum of all the numbers.

Step-by-step explanation:

sum of the ratios=2+3+5+7=17

the two largest number are 91 and 65

suppose we take 91 and 65 as the two largest numbers and 17 as the sum of the ratios. let it be 17x. now 7x is the largest ratio so it must be the largest number as well. now to find value of 1x we have to divide=91/7=13 now to confirm that 1x=13 we can take second largest ratio which is also the second largest number 5=65/5=13 so value of 1x=13

now 2x=2*13=26

3x=3*3=39

sum of all the numbers=26+39+65+91=221 hence answer is 221 is the sum of all the numbers.
