John shifted the decimal point of a number twice to the left to obtain a new number. The difference between the new number and the original number was 136.62.
a) How many times the new number is the original number?
b) What is the sum of the 2 numbers?
Solution
a)
Answer: 100 times
b)
Original number --> 1 unit
New number --> 100 units
100 units - 1 unit --> 136.62
99 units --> 136.62
99 units --> 136.62
1 unit --> 136.62 divided by 99 = 1.38
Sum of the two numbers
--> 100 units + 1 unit = 101 units
101 units --> 101 x 1.38 = 139.38
Answer: 139.38
