Question

in a cricket match kapil took one wicket less than twice the number of wickets taken by ravi.if the product of the number of wicket taken by this two is 15. find the number of wicket taken by each

Answer 1

Ravi took 5wickets. Kapil took 3wickets.
Because kapil have 3(^2)-1=5.

Answer 2

let no. of wickets taken by Ravi be x
let no. of wickets taken by Kapil be 2x-1
Acc. to question
(2x-1)*(x)=15
2x^2-x=15
2x^2-x-15=0
2x^2 -6x+5x-15=0
2x(x-3)+5(x-3)=0
(2x+5) (x-3)
x=-5/2; x=3
wickets can not be in negative and fraction thus, wickets taken by Ravi is 3 and
by Kapil
2x-1
2(3)-1
= 5
wickets taken by Kapil = 5
