Answer: B) Rs. 441 Explanation: Given principal amount = Rs. 8000 Time = 3yrs Rate = 5% C.I for 3 yrs = 8000 x 105100 x 105100 x 105100 - 8000= Rs. 1261   Now, C.I for 2 yrs = 8000 x 105100 x 105100= Rs. 820    Hence, the required difference in C.I is 1261 - 820 = Rs. 441

Answer: C) Arunachal Pradesh Explanation: The Dibang Wildlife Sanctuary is one of the eight wildlife sanctuaries of Arunachal Pradesh, India.

From given data, (C.P. of 17 balls) - (S.P. of 17 balls) = (C.P. of 5 balls) C.P. of 12 balls = S.P. of 17 balls = Rs.720. Hence, C.P. of 1 ball = Rs.720/12 = Rs. 60.

Answer: A) Autotrophs Explanation: Plants make their own food through the process of photosynthesis. Plants are self-sufficient. Green plants have the ability to prepare their own food and this is the reason why they are called autotrophs.                                          They make their own food through the process of photosynthesis using light energy to make sugars from carbon dioxide (C02) and water (H20). The chlorophyll which is present in the leaves is the main reason for the production of food in the plants and it is the reason for the greenery of the leaves too.

Answer: A) 36 kmph Explanation: Let the speed of goods truck be 'p' kmphDistance covered by goods truck in 10hrs (4+6) = Distance covered by other truck in 4 hrs. 10p = 4 x 90p = 36kmph.Therefore, the speed of the goods truck is p = 36 kmph.

Answer: A) Violet Explanation: In VIBGYOR. It has colors ordered from highest to lowest frequency.                 Violet > Indigo > Blue > Green > Yellow > Orange > Red   That says Violet has the highest frequency. We know, Speed of light = Frequency x Wavelength => As frequeny is inversely proportional to wavelength i.e, as frequwncy goes high wavelength goes down.   So, the violet color has the highest frequency.

Answer: D) Nagpur Explanation: With India's pledge to go all electric by 2030, Nagpur will be the first city in the country to adopt electric cabs as the country moves a step closer to its goal. The pilot project will see around 200 e-cabs in Nagpur with the local body to provide for the charging stations across the city. Currently, Mahindra and Honda are few of the car-manufacturers who have electric and hybrid vehicles in their line-up. We do hope that the situation changes, as hybrid and electric vehicles will help in the growing pollution in India. Countries such as France, Netherland and Belgium have already started to adopt electric and hybrid vehicles.
