The answers in options needs to be considered while answering the question. The total number of horses and soldier in the troop is 45. Let us consider option A with 40 soldiers = 80 human legs so the balance legs are 30 which is not possible for horses as they have 4 legs.
Going by option B= 35 soldiers = 70 human legs. So the balance legs remains 40, which is possible for 10 horses. Now the total number of horses and soldiers are 45 so 35 soldiers+10 horses = 45 and hence is a right answer. The balance options can be checked in similar way and will be found incorrect.

The level of the question is certainly not for Class 3. It involves use of simultaneous equations. Answer is 35 soldiers.

Class : Class 5

The way I taught my child was to try with each option, that is, start with option A, assume 40 is the number of soldiers, then calculate no of legs of soldiers, then minus that from total no. of legs, and see if the resulting number gives u the required number of horses you need in order to get a total of 45 horses and soldiers.
Repeat the same for option B, C and D.
Answer is B. This is how we did it:
Assume 35 as no. of soldiers
35x2 = 70 legs of soldiersM
Minus 70 from 110 (total legs)= 40 legs
40 horses legs = 40 divided by 4 =10 horses
Therefore 35 soldiers and 10 horses = 45 soldiers and horses totally

3 years = 36 months, and EMI paid each month= 1970/-, so the total amount paid in EMI is 36 x 1970, which is 70920.
Therefore, total value of the car is 35000 + 70920 = 105920/-.
