Question

If 66 2 3 % of a is equal to 16 2 3 % of b. Value of b is 1800 more than a. Find value of a

Answer 1

66⅔ % of a = 16⅔ % b

and b=a+1800

=>a × 66.6/100 = b × 16.6/100

=>66.6 × a=16.6 × b

By multiplying 10 on b.s.,

=>666/166=b/a

=>4.01=(a+1800)/a

Let 4.01≈4.

=>4a=a+1800

=>4a-a=1800

=>3a=1800

Thus,

a=600.

=>b=1800+a

=1800+600

=2400.
