Ques:- A train 240 m long passed a pole in 24 sec. How long will it take to pass a platform 650 m long?
Recent Answer : Added by dumeel kuppam vavvaalu On 2021-08-25 14:15:33:
From the first statement
Speed=distance/time
=>240/24=10m/s
so speed=10m/s
From the second statement
distance=length of the platform+length of the train=650+240=890m
Time=distance/speed
here, the speed of the train is already calculated
=>890/10=89s
So the time taken by the train to cross the platform is 89 seconds
Ques:- One half of a two digit number exceeds its one third by 6. Find the sum of the digits of the number?
Recent Answer : Added by Sohini Mitra On 2022-09-02 17:02:37:
Let the number be 10Y+X
(10Y+X)/2 = (10X+Y)/3+6
(10Y+X)(1/2-1/3) = 6
10Y+X = 36
Therefore, sum of the digits = 3+6 = 9

Ques:- A computer shop consists 3 brands laptop. Laptop of brand A is sold 3/16, B is sold 1/16 and C is sold 3/4 then what fraction is sold by the shop in all.
Recent Answer : Added by jay On 2022-08-14 16:45:19:
Answer: 1 / 3
Lets say each brand had 16 laptops
So Sold : A = 3 , B= 1 and C = 12 , total sold: 16 ,
Since each brand has 16 , total = 48
so 16/ 48 = 1/3 is the sold fraction

Ques:- Old Man Wrinkle Man Wrinkle spent 1/4th of his life as a boy, 1/8th as a youth, and 1/2 as an active man. If Man Wrinkle spent 8 years as an old man, then how many years did he spend as an active man?
Recent Answer : Added by Emad Samy On 2021-09-14 15:42:00:
32
Solution:
life as a boy = 1/4
life as a youth = 1/8
life as an active man = 1/2
sum of life as boy, youth and active man = 1/4 + 1/8 + 1/2 = 7/8
life as an old man = 1 − 7/8 = 1/8
1/8 Wrinkle’s life (as an old man) is 8 years.
and 1/2 = 1/8 *4
So, 1/2 Wrinkle’s Age (as active man) = 8*4 = 32years.

D. 12 : 11
Recent Answer : Added by larissa On 2022-08-14 16:34:02:
the ratio is 4 : 3
so -> let’s suppose a case where multiplying both sides for the same number, the sum of the result will be 28 …
4 * 4 = 16
4 * 3 = 12
16 + 12 = 28
in 8 years they will be respectvely 24 and 20
which is the same as 6/5
