Question

The sum of two numbers is 32.1. If one of them is twice the other, what are the numbers? ( A ) 10.7, 21.4 ( B ) 10.3, 21.8 ( C ) 12.4, 19.7 ( D ) 15.3, 16.8

Answer 1

Answer:

A

Step-by-step explanation:

let 1st no be x

othe =2x

sum =32.1

3x=32.1

x=10.7

other no =21.4

Answer 2

Answer:

Let the 1st no. be x

then the 2nd no. be 2x

total sum = 32.1

A/q

x + 2x = 32.1

=> 3x = 32.1

=> x = 32.1/3

= 10.7

Now,

1st no. = x = 10.7

2nd no. = 2x = 2×10.7 = 21.4

Hence , the two numbers are 10.7 and 21.4 .

Hope it helps you....
