Question

2. The difference between two numbers is 600. The bigger number is increased by 50 and the
smaller number is increased by 70. What will be the new difference?
a) 580 b) 620 c) 650 d) 720

Answer 1

Answer: according to the question:

Let the bigger number be x and smaller number be y then,

x-y=600

x=600+y

A.t.q

(x+50)-(y+70)= their difference

Now substitute the value of x in the following eq.

Answer is 580.

A) 580

• Difference between two numbers is 600

• The bigger number is increased by 50

• The smaller number is increased by 70.

${\boxed{\tt {\red {Solution:-}}}}$

Let the number be x and y

Here, x = larger number and y = smaller number.

ATQ,

= x - y = 600

Let's assume x = 800 and y = 200

= 800 - 200

= 600

_____________________________________

Now, coming to the question we have to find the difference between new number where ,

= x + 50 and y + 70

Using the above criteria assume x as 800 and y as 200

= x + 50

= 800 + 50

= 850

= y + 70

= 200 + 70

= 270

Now, for the difference

= (x + 50) - (y + 70)

= 850 - 270

= 580

${\blue{\underline {\bf{Thus\:option\:a)580\:is\:correct}}}}$
