Question : 62 of 100

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 numbers be x and y,
then
x + y =

46/3

And x - y =

14/3

So,
2x =

46/3+14/3=60/3

⇒ x = 10
y =

46/3

- 10 =

16/3

Therefore, xy = 10 ×

16/3

=

53 1/3
