If a/3=b/4=c/7, then a+b+c/c is 

Detailed Solution for Test: Ratio And Proportion, Indices, Logarithms - 4 - Question 10

a/ 3 = b/ 4 = c/7

a/c = 3/ 7 ; b/ c = 4/7

(a+b+c) / c ⇒ a/ c+ b/ c + 1

⇒ 3/7 + 4/7+ 1 

⇒ 1 + 1

⇒ 2

The sum of the ages of 3 persons is 150 years. 10 years ago their ages were in the ratio 7:8:9. Their present ages are 

Detailed Solution for Test: Ratio And Proportion, Indices, Logarithms - 4 - Question 19

GIVEN

The sum of the ages of 3 persons is 150 years. 10 years ago their ages were in the ratio 7:8:9.

TO FIND

Their Present ages

SOLUTION

Let the ages of the person 10 yrs ago be 7x, 8x, 9x according to the question.

Present ages will be 7x + 108x+10 and 9x + 10

Now according to the Question,

(7x + 10) + (8x + 10) + (9x + 10) = 150

=> 24x + 30 = 150

=> 24x = 150 - 30

=> 24x = 120

=> x = 5

Therefore Present ages are

7x + 10 = 45yrs

8x+10 = 50yrs

9x + 10 = 55yrs

Hence their Present Ages are 45,50 and 55yrs. (ANS)
