Maths and Logical Reasoning Test- 5 - CAT MCQ

Given: Green ball =5

Yellow ball =7

Red ball =4

Total ball =5+7+4=16

Probability that all the balls are of same colour

Hence, the correct option is (D).

Given:

We know that,

Hence, the correct option is (A).

P can do a piece of work in 15 days.

Part of work P can do in a day = 1/15

Q can do a piece of work in 20 days.

Part of work Q can do in a day = 1/20

Let, R can do a piece of work in x days.

Part of work R can do in a day = 1/x

P, Q and R together can do the work in 5 days.

∴ R can do a piece of work in 12 days.

Hence, the correct option is (B).

Let, the average of an inning =x

Total runs scored in 9 innings =9x

Total runs scored in 10 innings =9x + 10

New average

since average increases by 8 ,

Average after 10 innings =20+8=28

Hence, the correct option is (C).

Given: Cost price of 16 fruits = Rs 24

Sale price of 8 fruits = Rs 18

∴ Sale price of 16 fruits = Rs 36

Profit = Sale price − Cost price

= 36 - 24 = Rs 12

Thus, required gain percent

Hence, the correct option is (A).

Given:

Time = 4th Feb, 2005 to 18th April, 2005

= (24+ 31+18)days = 73 days

= 73/365 year = 1/5 year

P= Rs. 3000 and R = 25/4% p.a

Hence, the correct option is (D).

This question follows the following pattern:

So, YMA is the missing term in the series.

Hence, the correct option is (B).

Given series:

2, 3, 11, 38, __, 227, 443

The pattern followed is,

2 + 1³ = 3

3 + 2³ = 11

11 + 3³ = 38

38 + 4³ = 102

102 + 5³ = 227

227 + 6³ = 443

Hence, the correct option is (C).

Each of the Teacher, Doctor and Lawyer can work independently but the Manager needs to be associated to a company whether his own or owned by someone else.

Hence, the correct option is (D).

Given:

18 ÷ 2 - 25 × 9 + 6 = 38

(A) + and × → 18 ÷ 2 – 25 + 9 × 6 = 38

(B) + and ÷ → 18 + 2 – 25 × 9 ÷ 6 = - 17.5

(C) - and + → 18 ÷ 2 + 25 × 9 – 6 = 228

(D) ÷ and × → 18 × 2 – 25 ÷ 9 + 6 = 39.2222

Hence, the correct option is (A).

The series is:

17×1+1=18

18×3+3=57

57×5+5=290

290×7+7=2037

Hence, the correct option is (C).

Let the length of the platform and speed of train be x m and y km/h respectively.

According to the question:

y = 60 km/h

And,

x = 250 meters

Hence, the correct option is (B).

Pediatricians care for children from birth to young adulthood.

Similarly, Podiatrists care for problems in ankles and feet.

So, "ankle" is the correct answer.

Hence, the correct option is (A).

We will label the figure as shown below:

The horizontal straight lines are BC,IL,FH and DE, i.e. 4.

The lines sloping to your left are IM,FN,DO and AC, i.e. 4.

The lines sloping to the right are LO,HN,EM and AB, i.e. 4.

Thus, the number of straight lines =3 x 4=12

Hence, the correct option is (B).

Pigeon is a symbol of peace.

Similarly, the white flag is a symbol of surrender.

Hence, the correct option is (C).
