wrong answer (Question: 89220.0 )

15% of 690 = 103.05
12% of 250 = 30

than the sum of (103.05+30=133.05)+?=89
so ?=89-133.05

please review this Question.

Thanks

Hi Neeraj, you must know how to apply BODMAS Rule first to solve the questions of these types simplification...


(15% of 690 +12% of 250) ÷ ? = 89

or, {(15/100)x690 + (12/100)x250 } / ? = 89

or, (10350+3000)/100 = 89 x ?

or, 13350/8900 = ?

So, ?= 1.5
