Question
John had to multiply 'a' by 'b'. He however multiplied
'a' by 22.5 and obtained 423 as the product. Selina also had to multiply 'a' by 'b'. She however multiplied 'b' by 22.5 and obtained 558 as the product. What is the value of "ab"?Solution
According to question, => a x 22.5 = 423 => a = 423/22.5 ------ (i) Now, => b x 22.5 = 558 => b = 558/22.5 ------ (ii) Value of ab = (423/22.5) x (558/22.5) = 466.24
