Detailed Solution for RRB NTPC CBT 1 Question Paper (Held On: 28 Dec 2020 Shift 1) - Question 15

Given:

a3 - b3 = 125

a2 - b2 = 25

a + b = 5

Formulas used:

a2 - b2 = (a + b) (a - b)

a3 - b3 = (a - b) (a2 + ab + b2)

Calculation:

a2 - b2 = 25

⇒ (a + b)(a - b) = 25

⇒ 5(a - b) = 25

⇒ (a - b) = 5

a3 - b3 = 125

⇒ (a - b) (a2 + ab + b2) = 125

⇒ 5 × (a2 + ab + b2) = 125

⇒ (a2 + ab + b2) = 125/5 = 25

Detailed Solution for RRB NTPC CBT 1 Question Paper (Held On: 28 Dec 2020 Shift 1) - Question 16

Given:

The greatest number that will divide 155, 260, 315 and leave the remainder 5, 10 and 15

Calculation:

In order to make 155, 260, and 315 divisible by the greatest number, we need to subtract 5, 10, and 15 from each term respectively.

155 - 5 = 150, 260 - 10 = 250, 315 - 15 = 300

Now HCF of 150, 250 and 300:

150 = 2 × 3 × 5 × 5

250 = 2 × 5 × 5 × 5

300 = 2 × 2 × 3 × 5 × 5

Hence, HCF of 150, 250 and 300 = 50

∴ The greatest number that will divide 155, 260 and 315 and leave the remainder 5, 10 and 15 respectively is 50.

A train leaves station A towards station B at the speed of 50 km/hr. After half an hour, another train leaves station B towards station A at 150 km/hr. The distance between the stations is 725 km. The distance of the point from station A where the two trains are to meet is:
Detailed Solution for RRB NTPC CBT 1 Question Paper (Held On: 28 Dec 2020 Shift 1) - Question 25

Given:

The speed of train which leaves station A = 50 km/hr

The speed of train which leaves station B = 150 km/hr

The distance between the two stations A and B = 725 km

Formula used:

Distance = Speed × Time

Relative Speed ( in opposite direction) = Speed I + Speed II

Meeting Time = Distance between the trains/ Relative Speed

Solution:

Relative speed of both the trains going in opposite direction = 50 km/h + 150 km/h

⇒ 200 km/h

Distance between the trains after half an hour of train leaving station A = 725 km - 50 km/h × 1/2 hours = 700 km

Meeting time = 700 km / 200 km/h = 7/2 hours

∴ Distance from station A where two trains are to meet = 25 km + 50 km/h × 7/2 hours = 200 km
