OPTION:-A) 20 because its simple decrease 2cm from 5cm ans is 3cm therefore, the insect crawls 3cm per second then 60 divided by 3 = 20,therefore ans =20 seconds

Answer : B

Solution
Insect moved (5 - 2) cm per 2 seconds = 3 cm per 2 seconds
It will move 60 cm in (2/3 x 60) = 40 seconds

Answer: C (36 kg)
The option C should be 36 kg and not 30 kg. Corrected the mistake.

Solution:
Let the weight of the small ball be x.
3x = 12 + x
2x = 12
x = 6
Weight of 5 balls = 12 + 6+ 6+ 6 +6 = 36kg

Answer: C (36 kg)
The option C should be 36 kg and not 30 kg. Corrected the mistake.

Solution:
Let the weight of the small ball be x.
3x = 12 + x
2x = 12
x = 6
Weight of 5 balls = 12 + 6+ 6+ 6 +6 = 36kg

Ans 4:

I think they are asking for the mass of all 5 balls together. The mass of small ball is 6 Kg. Hence the total mass = 12 + 6 + 6 + 6 + 6 = 36.

Ans 5:

Class : Class 4
left side weight is 12 + 6(small ball) = 6 + 6 + 6 ( which means 12 + 6 + 6 + 6 + 6 = 36)
