==>men = 12-4 = 8
if team needs 20% of women then men Will be 80%
consider u want to hire “x” men

(12+x)(80/100) = 8 + x
so, x= 8

Recent Answer : Added by Solver On 2021-08-28 11:27:19:
speed = distence / time
60km/hr=distance / 9 sec
km / hr to m / s==> 60*1000 / 1* 3600 = 16.667
16.667*9 = distance
150 m is the answer

Ques:- A man gets x/y of Rs.10 and y/x of Rs.10. He returns Rs.20. The Answer choices are a) He may not lose b) He may lose c) He always loses d) Cannot be Determined
Recent Answer : Added by Admin On 2020-05-17 12:02:08:
x and y can be equal to 1..
If so,then he gets 1/1 of Rs.10 which is equal to 10 and
again 1/1 of Rs.10=Rs.10..so,he gets total of 20..and
returns 20..so,no gain and no loss..
If x=1,y=2,he gets, 5+20=25..and returns 20..so he may not
lose..
So,whatever be the values of x and y,only these two answers
are possible..
so its a)He never loses..

Ques:- What is the sum of two consecutive even numbers, the difference of whose squares is 84?
Recent Answer : Added by Admin On 2022-09-29 16:21:46:
Let the numbers be x and x + 2.
Then, (x + 2)2 – x2 = 84
⇒ 4x + 4 = 84
⇒ 4x = 80
⇒ x = 20.
∴ The required sum
= x + (x + 2)
= 2x + 2
= 42
