Question

Three numbers non-divisible by each other are such that the product of the first two is 551 and product of the last two is 1073. Find their sum.
A) 75
B) 81
C) 85
D) 89​

Answer 1

here

if we visualize it by taking any no. x,y and z

it is said that

x×y=551....I)

y×z=1073..ii)

this shows

middle no. is common factor in both

1073=29×37

551=29×19

frim here we can say 29 is common in both,

if we see first and second equation

we can say

y=29

which is the middle no.

if y=29

then

from first we take out x=551/29=19

from second we can say z=1073/29=37

hence the numbers are,19,29,37

Answer 2

Answer:

The numbers are 19 , 29 and 37........

➡️ 19 × 29 = 551

➡️ 29 × 37 = 1073.

Hence, there sum = 19 + 29 + 37 = 85.
