you assumed that they together can copy 140 pages coz' 70 per head, which is wrong. its clearly mentioned 70 pages together. if you go by your way it would 140-50 = 90 which B can copy in 10 hrs. which is not right.Rather, 70-50 = 20, which B can copy in 10 hrs. so B would copy 26 pages in:(26/20)*10 = 13 hrs.

A = 50
A+B = 70
B = 70 -50 = 20
B = 20 For 10 Hours
20Pages = 10 hours
1 pages = 10/20 =1/2
26 pages =(26*1/2)
26 pages = 13 hoursSimeon

Total stamps are the l.c.m of 3,4,5,6 i.e 60 and 1 is the remainder in all the cases.. so the toal stamp is 60+1=61 now deviding 61 with 8 leaves the remainder 5so if he want to make it a group of 8 he ll be having 5 stamps left

The answer is "e" because the value "abcdefgh" will get one index for each letter as:a=0b=1c=2d=3e=4f=5g=6h=7And since %c is written in question der4 only one letter will be our answer... and is "e" coz its index is 4.

Distancetravelled by the bird=2000m
time taken=187.5 sec
=375/2 sec
speed is in the ratio of 1:2
dividing the time in the ratio of 1:2
time to=375/2(2/3)=125 sec
speed=distane/time=1000/125=8 m/sec
speed in thefro direction=16m/sec -
