Select the correct answer


Solution!
Since the catamaran is travelling in downstream the speed of the stream as a pin the speed of the ship so its speed is equals to catamaran speed+downstream speed. Which becomes 20+5=25 km/he. Now by applying a formula we get
Time=90/25. We get our answer which is 3.6

Select the correct answer


Solution!
Unit digit in 34 = 1  Unit digit in (34)16 = 1
 Unit digit in 365 = Unit digit in [ (34)16 x 3 ] = (1 x 3) = 3
Unit digit in 659 = 6
Unit digit in 74  Unit digit in (74)17 is 1.
Unit digit in 771 = Unit digit in [(74)17 x 73] = (1 x 3) = 3
 Required digit = Unit digit in (3 x 6 x 3) = 4

Question No 23

. A man has a certain number of small boxes to pack into parcles. If he packs 3, 4, 5 or 6 in a parcel, he is left with one over; if he packs 7 in a parcle, none is left over. What is the number of boxes, he may have to pack?

Select the correct answer


Solution!
Clearly, the required number would be such that it leaves a remainder of 1 when divided by 3, 4, 5, or 6 and no remainder when divided by 7. Thus, the number must be of the form (L.C.M of 3, 4, 5, 6) x + 1 i.e., (60x + 1 ) and a multiple of 7. Clearly, for x = 5, the number is a multiple of 7. So the number is 301.

Question No 30

84, 78, 72, 66, 60, 54, 48, ?, ?
What numbers should come next?

Select the correct answer


Solution!
In this simple subtraction series, each number is 6 less than the previous number.
Rule = (1st number), (1st no. - 6 = 2nd no.), (2nd no. - 6 = 3rd no.). . .
Now in our case,
(84), (84 - 6 = 78), (78 - 6 = 72), (72 - 6 = 66), (66 - 6 = 60), (60 - 6 = 54), (54 - 6 = 48), (48 - 6 = 42), (42 - 6 = 36).
So the answer is B = 42, 36.
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30
