With the extra competition on the rise, we are here to provide you Math Speed Booster Quiz to increase your speed in the Quant Section. Time management is one of the most important tasks in all competitive examinations. We all struggle to attempt maximum questions in the given time to have a niche over other competitors.

Quantitative aptitude is considered to be one of the toughest parts of any competitive exam. Although most of the candidates are afraid of this section, it can be the most scoring subject if prepared off well and attempted within the given time limit. In order to master this section of the examination, a few core skills need to be developed out of which Speed is a must.

Quantity I: No. of days in which A will work alone, given A and B can complete work in 8 days, B and C can complete work in 12 days, C and A can complete work in 8 days.

Quantity II: No. of days in which A will work alone, given A and B can complete work in 18 days, they started work together and after working for 6 days A left and B completed remaining work in 24 days.

Correct

Explanation:

LCM = 24

So A + B = 24/8 = 3

B + C = 24/12 = 2

C + A = 24/8 = 3 2

( A+B+C) = 3+2+3 = 8

A+B+C = 4

(A+B+C) – (B+C) = 4 – 2 = 2

So A = 24/2 = 12 days

A = 36 days

Incorrect

Explanation:

LCM = 24

So A + B = 24/8 = 3

B + C = 24/12 = 2

C + A = 24/8 = 3 2

( A+B+C) = 3+2+3 = 8

A+B+C = 4

(A+B+C) – (B+C) = 4 – 2 = 2

So A = 24/2 = 12 days

A = 36 days

Category: New Pattern Quadratic Equations

Quantity I: Volume, if diameter of sphere is 14 cm

Quantity II: Volume, if side of cube is 8 cm

Correct

Explanation:

Quantity I. Volume of sphere = (4/3)* Pie* R3 R=7 ;

Volume= 1437.33

Quantity II: V=a^3 = 8^3 = 512

I > II

Incorrect

Explanation:

Quantity I. Volume of sphere = (4/3)* Pie* R3 R=7 ;

Volume= 1437.33

Quantity II: V=a^3 = 8^3 = 512

I > II
