(4) 84%
(5) 88%

Solutions:

Ans.(1-5) Ans.1(5) Speed of car Q on day 1+ speed of car T on day 2
= 15 + 15 = 30 kmph
Speed of car P on day 2+ speed of car S on day 1
= 15 + 14 = 29 kmph
= Difference = 30 – 29 = 1 kmph
Ans.2(3) From the table option (3) is correct.
Ans.3(1) Ratio = Ans.4(2) distance travelled by car P on both days
= 210 + 171 = 381 km
distance travelled by car R on both days
= 32 4 + 132 = 456
Required %= Ans.5(4) Sum= (18 + 12) km/hr =30km/hr Ans.6(4) Required number of females
= 72000x 12/100 x (100-42-23)/100= 3024
Ans.7(2) Required % = (22+17)-(8+14)/(8+14)×100
= (39-22)/22 ×100
= 1700/22 = 77.27% = 77%
Ans.8(1) Required average = (72000×(16+12+11+14)/100×4
= 9540
Ans.9(5) Required difference = 72000 × ([(22+8)-17])/100
= 720×13 = 9360
Ans.10(4) Required % = 16/(11+8)×100 = 1600/19 = 84.21=84%
