A,B,C,D START AT THE SAME TIME TO RUN AROUND A CIRCULAR GARDEN IN THE SAME DIRECTION. A COMPLETES A ROUND IN 30 MIN, BIN 60 MIN,C IN 90 MIN AND D IN 105 MIN. AFTER WHAT TIME THEY WILL MEET AGAIN AT THE STARTING POINT?
A)15 HRS B) 10 HRS C) 21 HRS D) 20 HRS

Reply Like? Yes (7) | No

(10 years ago)

answer is 21 hours

the meeting time is lcm of all the individual times because all the numbers are divisible by the lcm. so at that time all will have completed an integral number of rounds.

so the lcm is 1260 min which is 21 hrs

Like? Yes | No

(10 years ago)

Lcm of 30,60,90,105=1260 min/60= 21 hrs

Like? Yes (1) | No

(10 years ago)

answer is 1260 mins or 21 hrs .
Take the l.c.m of 30,60,90 and 105 you will get the result .

Like? Yes | No

LCM of those numbers gives the result-1260(min)

but ans is : -3 how ?

Like? Yes | No

(10 years ago)

when u subtract 39-40=-1
37-39=-2
33-37=-4
26-33=-7
15-26=-11 so when u add first two number -1-2=-3
-3-4=-7
-4-7=-11
-7-11=-18
the number -18 tells the answer as -3 after 15...because if u put -3 after 15(can be considered as -3-15=-18)...i think u will get this

Like? Yes (4) | No

(10 years ago)

answer should be -1

the difference between terms are as 1,2,4,7,11
let us name this series as A

the difference between terms of series A is 1,2,3,4,
lets term this series as B
so the next term in series B is 5
which makes next term in series A as 16
which means the next term in original series is 15-16=-1
so the answer is -1

a num divided by 357 reminder 5 then same num divided by 17 what is the reminder ?

Reply Like? Yes | No

(10 years ago)

357 is divisible by 17 so that remainder is 5

Like? Yes | No

(10 years ago)

let x be the number
as x leaves remainder 5 when divided by 357
so x=357a+5
here a is the qoutient
when number is divided by 17 we get
x/17 = (357a+5)/17 = 21a+5/17
so we see that 5 is the remainder.
