Top 100+ Nagarro Aptitude Interview Questions And Answers

Question 1. A Sphere And A Cube Have The Same Surface Area. Find The Ratio Of Their Volumes?

Answer :

SA of a sphere: 4πr² 

SA of a dice: 6x² 

4πr² = 6x² 

r²/x² = 6 / 4π 

(r/x)² = 3 / 2π 

r/x = (three / 2π)^zero.Five 

Volume of a sphere: 4/three πr³ 

Volume of a cube: x³ 

Find the ratio which means (four/three πr³)/x³ 

= (4π/three)(r³/x³) 

= (4π/3)(r/x)³ 

= (4π/three)(3 / 2π)^1.Five 

= (2²π/three)[3^1.5 / (2^1.5)(π^1.5)] 

= √2√three / √π 

= √(6/π).

Question 2. Four Horses Are Tethered At four Corners Of A Square Plot Of Side 63 Meters So That They Just Cannot Reach One Another. The Area Left Ungrazed Is?

Answer :

region of rectangular = sixty three*sixty three=3969 m^2

location inside the rectangular this is grazed =4*place of quadrants of 4 circles 

= four*(1/four)*(22/7)*(63/2)*(63/2) =3118.5

vicinity left ungrazed = 3969-3118.5=850.Five.

Question 4. A Train 360 M Long Is Running At A Speed Of forty five Km/hr. In What Time Will It Pass A Bridge one hundred forty M Long?

Answer :

Formula for converting from km/hr to m/s: X km/hr = X *( five/18) m/s.

So Speed = 45 * five/18 m/sec = 25/2 m/sec.

Total distance to be covered = (360 + one hundred forty) m = 500 m.

Required time = 500 * 2/25 sec = 40 sec.

Question five. The G.C.D. Of 1.08, zero.36 And 0.Nine Is?

Question 6. The Slant Height Of A Right Circular Cone Is 10 M And Its Height Is 8 M. Find The Area Of Its Curved Surface?

Answer :

l = 10m

h = 8m

so r = √(l^2 - h^2) = √(10^2 - 8^2) = 6m 

So Curved surface region = (π * r * l) = ( π * 6 * 10) m2 = 60π m2.

Question 7. How Many Times In A Day, Are The Hands Of A Clock In Straight Line But Opposite In Direction?

Answer :

The palms of a clock factor in opposite directions (within the identical directly line) eleven times in each 12 hours. (Because among five and 7 they factor in opposite guidelines at 6 o'clock only).

Now, we should arrange eight letters, out of which M happens twice, T occurs twice and the relaxation are distinct.

So,Number of methods of arranging those letters = (eight!/2!*2!)=10080.

Now, AEAI has 4 letters wherein A occurs 2 instances and the rest are one of a kind.

Number of methods of arranging these letters = (four!/2)=12.

=> Required wide variety of phrases = (10080 * 12) = 120960.
