Question : 144 of 200

Marks: +1, -0

The sum of two numbers is

15 1/ 3

and their difference is

4 2 /3

. The product of the numbers is

$53 1 /3$
60
$48 2/ 3$
50

Solution:

(1) Let the two number be x and y, then

x+y= {46}/{3}

And

x-y= {14}/{3} .

So

2 x= {46}/{3}+ {14}/{3}= {60}/{3} ⇒ x=10

y= {46}/{3}-10= {16}/{3}

Therefore,

x y=10 ×{16}/{3}=53 {1}/{3}
