In the growth rate the pattern followed is:

3.5 + 0.2 = 3.7

3.7 + 0.2 × 2 = 3.7 + 0.4 = 4.1

4.1 + 0.4 × 2 = 4.1 + 0.8 = 4.9

4.9 + 0.8 × 2 = 4.9 + 1.6 = 6.5

Now, 6.5 + 1.6 × 2 = 6.5 + 3.2 = 9.7

Thus 9.7 is the answer.

The pattern followed is as follows:

Thus jmgk is the answer.

I. No mats are sofas = clearly follows.

II. All chairs can possibly be tables = its possible, hence true( Possibility shown below.)

The greatest prime number less than 100 is 97. The least prime number is 2.

Difference = 97 – 2 = 95

Similarly, if we rotate direction indicator through 135⁰ in clockwise direction then pointer indicating South would show North – West direction.

Time taken by A , B and C to fill/empty the tank completely = 10 , 12 and 20 hours respectively

Hence part of tank filled by A, B and emptied by C in 1 hour = 1/10, 1/12 and 1/20 respectively

Part of tank filled by all 3 pipes in 1 min =1/10+1/12−1/20=1/10+1/12−1/20

=660+560−360=660+560−360

=860=860

= 2/15

Hence it will take 15/2 hours ie 7 hours and 30 mins to completely fill the tank

Total students = 50

Student who play hockey = 25

Student who play football = 30

Students who play neither football nor hockey = 8

Total students = (Student who play hockey) + (Students who play football) – (Students who play both hockey and football) + (Students who neither play hockey nor football)

50 = 25 + 30 – (Students who play both hockey and football) + 8

Students who play both hockey and football = 13

So, total 13 students play both hockey and football.

Here, According to the Venn diagram,

Doctors who are not  Engineers but Good speakers = 6.

Actual amount they have to got -

But mistakenly they got the amount in the ratio = 3 : 4 : 2

Hence, A and B gained in the transaction.

208, 225, 259, 310, ?, 463

225 – 208= 17

259 – 225= 34

310 – 259= 51

The value increases in multiples of 17.

The next number will be increased by 68, 310 + 68 = 37

Hence the correct option is 378
