Question
Study the given pattern carefully and select the number
that can replace the question mark (?) in it.Solution
Logic is : (First number x 10) + (Second number x 5) = Third number. First row = (12 x 10) + (9 x 5) = 120 + 45 = 165 Second row = (14 x 10) + (10 x 5) = 140 + 50 = 190 Third row = (17 x 10) + (7 x 5) = 170 + 35 = 215
