  1. If doubling a number and adding 20 to the result gives the same answer as multiplying the number by 8 and taking away 4 from the product, the number is :
    1. 2
    2. 3
    3. 4
    4. 6
Correct Option: C

Let the number be x.
∴  According to question,
2x + 20 = 8x – 4
or 8x – 2x = 20 + 4
or 6x = 24
∴  x = 4
