Maths Questions for KVS Exam 2017_70.1
S4. Ans.(a)
Sol. To solve such questions, we keep 99 as it is in second part, but in part first, we convert all 9’s into zeros. 
S5. Ans.(a)
Sol. 50/108=100/y
y = Rs. 216
S6. Ans.(a)
Sol. 
Required number = H.C.F of (1356 – 12), (1868 – 12) and (2764 – 12) 
= H.C.F of 1344, 1856 and 2752 = 64.
S7. Ans.(a) 
Sol. 
Speed of the first man = 32 km/hr
Time taken = 192 ÷ 32 = 6 hr 
Second man covers 192 km in 3 hr 
∴ Speed of the second man 
= 192 ÷ 3 = 64 km/hr 
Ratio = 32 : 64 or 1 : 2 
S8. Ans.(c)
Sol. 
Distance already covered = (3/4) × 12 = 9 km
Time spent = (2/3) × 45 min = 30 min
Distance left = (12-9) km = 3 km
Time left = (45-30) min = 15 min
∴ Required speed =3/ (15/60) km/hr
= 12 km/hr 
S9. Ans.(b)
Sol. 
Total distance covered = 90 × (5/18) × 38 = 950 m
So, length of bridge = 950 – 287 = 663
S10. Ans.(d)
Sol. 
Since the sum of the length of the train and the engine is needed, so both the lengths must be known.
