A to P = 7s

jis mein john nay 2s waste karay ..

so time becomes 7-2s for the travelling of ball = 5s.

hahaha yeh question kara hua hai :D

(10/x)+(15/x+0.5)=5
(10(x+0.5) + 15x)/x(x+0.5)=5
10x+5+15x=5x(x+0.5)
25x+5=5x^2+2.5x
5x^2-25x+2.5x-5=0
5x^2-22.5x-5=0

divide by 2.5

2x^2-9x-2=0 Answer


AB MERAY SAWAAL KA JAWAB DOO :D

yar in this question I think we just have to square the lengths

Q7 (a) (ii) (b) area apr/ area abc => square lenght of AP/ square lenght of AB => ap = ab-pq => 5-4=1

therefore 1^2/5^2 => 1/25


hope it is corrrect

Yaar i thought the same ...

but 3/25 aaraha hai answer ..
