Obtain the formula fort the statement : when thrice a certain number is subtracted from 64, the result is 28.
2 - 3 x = 64
64 - 3 x = 28
28 = 3x + 64
None of these

Frame a formula " The product of 3 consecutive numbers ( the smallest being x) is 310.
x × ( x + 1) × (x + 3) = 310
x × (x + 2) × (x + 4) = 310
x × (x + 1) × (x + 5) = 310
(x + 1) × (x + 3) × (x + 5) = 310
