Answer 1

1.(a) Let the pages he read for the first

be x.

On the second day he read x/2 pages.

Similarly, on the third day he read, (x/2)/2

pages, that is, x/4

And on the fourth day he read x/8 pages.

So the equation becomes,

x + x/2 + x/4 + x/8 = 300

⇒8x/8 + 4x/8 + 2x /8 + x/8 = 300

⇒15x = 2400⇒x = 160.

∴ He read 160 pages on the first day.

(b)

• Books educate us
• Books keep the brain healthy

2.(a) Total profit is 2000. Let us consider

the profit on wall hangings to be x.

Now we get the profit on Dupattas be

2x-30 and the profit on hand bags be

2x+80.

Now we get 2x - 30 + 2x + 80 + x = 2000

⇒ 4x + 50 = 2000⇒ 4x = 1950

⇒ x = 487.5

∴ The profit made from wall hangings is 487.5
