Question

How many numbers are there in the series of 2 to 20 if the sum is 143

Answer 1

Answer:

If two numbers are in the ratio of 2:3 have the sum of 143, then what is the number

Let the rational between two numbers be x

Hence the two numbers are 2x and 3x. They have sum of 143. Accordingly

2x + 3x = 143

5x = 143

x = 143 / 5

x = 28.6

The rational is 28.6, hence two numbers are

One number 2x = 2 × 28.6 =57.2

2nd number 3x = 3 × 28.6 = 85.8

Answer the two numbers are 57.2 and 85.8

To check the correctness of answer, we check their sum, which should be 143

57.2 + 85.8 = 143

Hence answer is correct.
