(b) 1 : 2
(c) 2 : 1
(d) 3 : 2
(e) None of these

(b) 76.8°
(c) 75.6°
(d) 45.5°
(e) None of these
Q15. If the production of rice is 5 times that of jowar and the production of jowar is 2 times that of bajra, then the ratio between the yield per acre of rice and bajra is:
(a) 5 : 2
(b) 3 : 1
(c) 4 : 1
(d) 6 : 1
(e) None of these
S2. Ans.(e)
Sol. Marks obtained by B in Maths and English = 30 + 90 = 120
Marks obtained by D in maths and english = 40 + 70 = 110
Difference = 120 - 110 = 10
S3. Ans.(a)
Sol. Marks obtained by A in Geography = 50
Marks obtained by A in Hindi = 70
Required % = 50/70 * 100 ≈ 71 %
S4. Ans.(c)
Sol. Total marks obtained = 60 + 90 = 150
Total marks = 200
Percentage marks = 150/200 * 100 = 75%
S6. Ans.(d)
Sol. The speed of vehicle B on both the days is 43 km/h.
S7. Ans.(c)
Sol. Speed of A on first day = 52 km/h
Speed of C on first day = 63 km/h
∴ Difference = 65 – 52 = 11 km/h
S8. Ans.(e)
Sol. Speed of vehicle C on second day = 45 km/h
=45×5/18=2.5×5 = 12.5 m/sec
S12. Ans.(a)
Sol. ∴ 100% = 360°
∴ 50% = 180°
∴ Wheat + rice + maize = 72° + 72° + 45° = 189° > 180°
S13. Ans.(c)
Sol. Required ratio = 72° : 36° = 2 : 1
