5 is added to a certain number, the sum is multiplied by 7, the product is divided by 5 and 5 is subtracted from the quotient. The remainder left is half of 66. What is the number?  Select the correct option.
A) 21  B) 20  C) 22  D) 30  E) 45
Let number is X.   When 5 added to it,   = (X+5)   7 multiplied to sum,   = 7 *(X +5)   Now,   = [{7 *(X +5)} /5]   And,   = [{7 *(X +5)} /5] - 5   According to question,   [{7 *(X +10)} /5] - 5 = half of 66   [(7X + 35) /5) = 33 +5   7X + 35 = 38 *5   X = 155/7   X = 22.14=22   So, required number is: 22.   ANSWER : 22
