@snkr87 8/3
@snkr87 said: Two pipes A & B can fill a tank in 6hr & 8hr respectively. If both the pipes are opened together, then after how many hrs should B be closed so that the tank is full in 4 hr...?opt 2/(8/3)/(2/3)/1
8/3??
my method:
A=V/6 , B=V/8
now A+B=7V/24
let them rum for t hr
(7Vt)/24 + (4-t)V/6 = V
solve
@truly.gone bhai sach baat toh ye hai ki user name nai mil raha tha toh gusse mein keyboard pe jitne numeric value mile sab laga diye.
There are 5 consecutive integers in ascending order .The average of the first and twice the last is equal to the average of the other three.Find the first integer????
Rju went to the market to purchase three pens . the cost of the first pen was more than that of the second by 25% which was more than that of the third by 20%.If the average cost of the first two pens was rs 15 more than that of the last two pens, find the cost of th costliest pen ?
@truly.gone bhai phir toh kasfi costly hogi yaar....mein garib hu ...can't afford to hv costly lassi
@truly.gone hahahaha...tab toh 10 glass ka order deta hu.....abe tum kaha sunny ke saath ho be...wo lassi bana rahi hai aur tum aish kar rahe ho...
@JS-M take third asx now second is 6/5x and first is 3/2x
difference between the avg. is 15 solve accordingly...
@JS-M said:share approach plz....
(1.25(1.2x)+1.2x)/2=(1.2x+x)/2+15 ... solve for x and then for costlier pen(1.5x)
