Question

Mikel thinks of a number. He multiplies the number by 100, divides
it by eight then adds 6.50. The answer is 1206.5. What was his
starting number?

Answer 1

Answer:

the number is 96

Step-by-step explanation:

let the number be x

x*100/8+6.50

100x/8+6.50=1206.5

100x/8=1206.50-6.50

100x/8=1200

By cross multiplication,

100x=8*1200

100x=9600

x=9600/100

x=96

Answer 2

Answer:

Let the no. be x

Then Multiply by 100 is 100 x

Divided by 8

100x/8

12.5 x

Then add 6.5

Now 12.5x+6.5 = 1206.5

12.5 x = 1200

x= 1200/12.5
