Solution:
Speed of train P
On Day 1 – (980/20) = 49km/h
On Day 2 – (704/22) = 32 km/h
On Day 3 – (1127/23) = 49 km/h
Similarly, for train Q, the speed
On Day 1 – (720/15) = 48 km/h
On Day 2 – (1012/22) = 46 km/h
On Day 3 – (1120/20) = 56 km/h
Similarly, for train R, the speed
On Day 1 – (1044/18) = 58 km/h
On Day 2 – (1008/16) = 63 km/h
On Day 3 – (1254/22) = 57 km/h
Similarly, for train S, the speed
On Day 1 – (1026/18) = 57 km/h
On Day 2 – (855/15) = 57 km/h
On Day 3 – (741/13) = 57 km/h
Similarly, for train T, the speed
On Day 1 – (1140/20) = 57 km/h
On Day 2 – (1144/22) = 52 km/h
On Day 3 – (918/17) = 54 km/h
Similarly, for train U, the speed
On Day 1 – (871/13) = 67 km/h
On Day 2 – (1224/18) = 68 km/h
On Day 3 – (1518/23) = 66 km/h
1). Train S has the same speed on all three days.

2). The speed of train P on 1st day = 49 km/h
The speed of train S on 2nd day = 57 km/h
Difference = 57 - 49 = 8 km/hr

3). The speed of train Ron 2nd day = 63 km/h
Speed in metre per second = 63 x (5/18) = 17.5 m /s

4). On the 3rd day the speed of Train U = 66 km/h
On 1st day the speed of Train U = 67 km/h
Reqd% = (66/67) × 100 = 98.5 = 98%

5). Speed of Train Ton Day 2 = 52 km/h
Speed of Train U on Day 2 = 68 km/h
Reqd ratio = 52/68 = 13 : 17

6). Total flooring area with wood = 1287 + 156 = 1443 sq m
Cost of flooring area with wood =1443 x 170 = Rs. 245310
Total flooring area with marble = accounts room + record keeping cum-server room + pantry
Cost of flooring area with marble =743 x 190 = Rs.141170
Reqd ratio = (245310/141170) = (24531/14117) = 24531 : 11417

7). Area of wall = 2(15 x 13+ 15 x 12)= 750
Area of director's room = 13 x 12 = 156
Cost of painting = 190 x (750 + 156) = Rs.172140
Cost of flooring= 170 x 156 = Rs.26520
Total cost = 172410 + 26520 = Rs. 198660

8).Total area of the institute = 2500 sq m
Remaining area = 2500 -2186 =314 sq m
Cost of renovation of the remaining area  =314 x210 = Rs. 65940

9). Area not to be renovated = 314 sq m
Reqd % = (3.14/2500)x100 = 12.56

10). Cost of renovation of the hall =1287 x 170 = 218790
Cost of renovating the accounts room = 276 x 190=52440
Total cost = 218790 +52440 =Rs. 271230
