Sushil was thrice as old as Snehal 6 years back. Sushil will be time as old as Snehal 6 years hence. How old is Snehal today.

let Snehal's age 6 years back =x

content, sushil's age 6 years back = 3x

(5 / 3)( x + 6 + 6 = (3 x + 6 + 6)

so 5 (x + 12 )= 3(3 X + 12)

so x = 6, Sanaya age = x+ 6

years = 12 years

A 1000 m long train crosses a platform 100 seconds while it crosses a single pole in 20 seconds. What is the length of platforms?

Speed=1000/20

Speed=500m/s

Let the length of platform be x metres

Then,(x+1000)/100=500

X+1000=500*100

X+1000=50000

X=50000-1000

X=4900 m

In a family, there are six members A, B, C, D, E and F. A and B are a married couple, A being the male member. D is the only son of C, who is the brother of A. E is the sister of D. B is the daughter-in-law of F, whose husband has died. How is F related to C?

Option (C) A is a male and married to B. So, A is the husband and B is the wife. C is the brother of A. D is the son of C. E, who is the sister of D will be the daughter of C. B is the daughter-in-law of F whose husband has died means F is the mother of A. F is the mother of A and C is the brother of A. So, F is the mother of C.

In alphabet series, some alphabets are missing which are given in that order as one of the alternatives below it. Choose the correct alternative. c _ baa _ aca _ cacab _ acac _ bca

The series is cab / aa / cacab / cacab / aa / cacab / ca. Thus, the pattern cacab, cacab, aa is repeated

X - Z means X is a mother of Z;

. 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?

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.

Price of perfumes is giving in discounted price with 30% but after a month price increases 30% again now what will the new price of perfumes?

Let price of perfume is 100.

Discount 30% =70

The average weight of 8 cats is 4 kg. If the weight of 2 dogs be included, the average rises by 600 g.The average weight of dogs is :

Average weight of dogs:

=total weight with dogs-total weight of cats

=(10Ã—4.6-8Ã—4)kg

=(46-32)kg

=14 kg is weight of both dogs.

=14/2

=7 is the average weight of dogs.

In following question, a number series is given with one term missing.

Choose correct alternative that will same pattern and fill in the blank spaces.

7, 6, 10 ,27, 104, ...

Choose correct alternative that will same pattern and fill in the blank spaces.

7, 6, 10 ,27, 104, ...

Here,

7 * 1 - 1 = 6

6 * 2 - 2 = 10

10 * 3 - 3 = 27

27 * 4 - 4 = 104

So 104 * 5 - 5 = 515.
