1.	4 is added to a number and the sum is multiplied by 5. If 20 is subtracted from the product and the difference is divided by 8,then the result is equal to 10. Find the number
Answer» ANSWER: $as \: per \: question \\ \frac{(x + 4) \times 5 - 20 }{8} = 10 \\ (x + 4) \times 5 - 20 = 10 \times 8 \\ (x + 4) \times 5 = 80 + 20 \\ (x + 4) = \frac{100}{5} = 20 \\ x = 20 - 4 = 16 \\ x = 16 \\ thus \: the \: number \: is \: 16$
