Explanation

In this type of question, We need to find out the LCM of the given numbers.

LCM of 12, 15, 18 and 20;

12=2×2×3;15=3×5;18=2×3×3;20=2×2×5;

Hence, LCM = 2×2×3×5×3

Since, the soldiers are in the form of a solid square.

Hence, LCM must be a perfect square. To make the LCM a perfect square, We have to multiply it by 5,

hence,

The required number of soldiers

= 2×2×3×3×5×5

= 900

Average temperature for Wednesday, Thursday and Friday = 40° C

Total temperature = 3 × 40 = 120° C

Average temperature for Thursday, Friday and Saturday = 41° C

Total temperature = 41 × 3 = 123° C

Temperature on Saturday = 42° C

Now,

(Thursday + Friday + Saturday) - (Wednesday + Thursday + Friday) = 123 - 120;

Saturday - Wednesday = 3

Wednesday = 42 - 3 = 39° C
