Question

The product of two numbers is 956.81. If one of the numbers is 29.35, find the other number (upto 1 decimal places)

• A. 39.5
• B. 39.1
• C. 39.5
• D. 39.9

Answer 1

The correct option is D 39.9

$\text{The product of two numbers}=X\times YX\times Y=956.81$

$\text{Let the given one number be X}=23.95$

$\text{We have to find the other number. Let the other number be Y}$

$\text{X}\times Y=956.8123.95\times Y=956.81(\because X=23.95)$

$\text{Y}=\frac{956.81}{23.95}$

Step 1: Get rid of decimal from the divisor.
$\frac{956.81}{23.95}=\frac{956.81\times 100}{23.95\times 100}=\frac{95681}{2395}$
Also, $\frac{95681}{2395}=95681÷2395$
Step 2: perform the long division, as you would with whole numbers as follows
Hence, the other number is 39.9
