Recent Answer : Added by Admin On 2022-09-29 15:59:24:
let the average of 25 person be x
total age of a person=average×no.of person
total age of 25 person=X×25
=25X
when a new person of 46kg come average decrease by 5kg(X-5)
Total age of 26 person =25x+46
Average age of 26 person=X-5
A/Q
.25X+46=26(X-5)
25X+46=26X-130
26X-25X=130+46
X =176
hence the av. of 25 person be 176kg
Ques:- A can do a piece of work in 12 days. When he had worked for 2 days B joins him. If the complete work was finished in 8 days. In how many days B alone can finish the work?
Recent Answer : Added by Admin On 2022-09-29 15:25:12:
The work done by A in 8 days is = 8/ 12 = 2/3
Means A alone completes 2/3 part of work.
Remaining work which is (1–2/3) = 1/3 is completed by B in 8–2 = 6 days
So the complete work done by B in 6/(1/3) = 18 days.
B alone can complete the work in 18 days.
Ques:- How long does a train 165 meters long running at the rate of 54 kmph take to cross a bridge 660 meters in length?
Recent Answer : Added by Nayana On 2022-09-23 18:07:00:
Speed of train = 54km/hr
= 54 x (5/18) m/s

Length of train = 165m
Time required to cross a bridge of 660m in length = (660+165) / 15
= 55 seconds

Recent Answer : Added by VSEC_me On 2022-08-14 16:34:00:
Let the total rotations be x:
So the distance covered by both the wheels will be same,
9 * x = 7 * (x + 10)
x = 35 rotations
distance travelled = 9 * 35 = 7 * (35 + 10) = 315 feet
