Question

(i) In what ratio should we increase 24 to obtain 32?
(ii) In what ratio should we reduce 100 to obtain 80?​

Answer 1

Given: The two numbers 24 and 100.

To find:

(i) In what ratio should we increase 24 to obtain 32?

(ii) In what ratio should we reduce 100 to obtain 80?​

Solution:

• Now we have given the number 24.

• Let x be the multiple , then:

                  24 × x = 32

                  x = 32/24

                  x = 4/3

• Now the next number is 100.

• Let x be the multiple , then:

                  100 × x = 80

                  x = 80/100

                  x = 5/4

Answer:

            So in 4/3 ratio should we increase 24 to obtain 32 and in 5/4 ratio should we reduce 100 to obtain 80.
