рд╡реНрдпрд╛рдЦреНрдпрд╛ :
Answer: C) 3 Explanation: When 16nis divided by 9, we have 1619, remainder = 7 1629, remainder = 4 1639, remainder = 1 1649, remainder = 7 1659, remainder = 4 1669, remainder = 1 So, we have cyclicity of 3 factors i.e 7,4,1. Hence only 3 remainders are possible.

рдЙрддреНрддрд░ : 2. "1"
рд╡реНрдпрд╛рдЦреНрдпрд╛ :
Answer: B) 1 Explanation: Let x be the number. Given: x = 296n + 75 [where n is quotient] --> (378n) +( 372 + 1) -->37(8n + 2) + 1 Hence, when x divided by 37, 1 is the remainder.

рд╡реНрдпрд╛рдЦреНрдпрд╛ :
Answer: D) 6 Explanation: When we divide 1234 by 8, remainder is 2 When we divide 1235 by 8, remainder is 3 When we divide 1237 by 8, remainder is 5 ---> 2 x 3 x 5 = 30 As 30 will not be the remainder because it is greater than 8, when 30 divided by 8, remainder = 6.
рдкреНрд░: There is an empty reservoir whose capacity is 30 litres. There is an inlet pipe which fills at 5 L/min and there is an outlet pipe which empties at 4 L/min. Both the pipes function alternately for 1 minute. Assuming that the inlet pipe is the first one to function, how much time will it take for the reservoir to be filled up to its capacity? 11410 05b5cc77ae4d2b4197775013d

рдЙрддреНрддрд░ : 3. "51 min"
рд╡реНрдпрд╛рдЦреНрдпрд╛ :
Answer: C) 51 min Explanation: The work to be done = Capacity of reservoir = 30 litres. 1st Minute ---> inlet pipe opened ---> 5 lit filled 2nd minute ---> inlet pipe closed; outlet pipe opened ---> 4 lit emptied In 2 minutes (5 litres - 4 litres = 1lit) is filled into the reservoir. It takes 2 minutes to fill 1lit ---> it takes 50 minutes to fill 25 litres into the reservoir. In the 51st minute inlet pipe is opened and the reservoir is filled.

рд╡реНрдпрд╛рдЦреНрдпрд╛ :
Answer: C) Option C Explanation: At 3 o'clock, the minute hand is 15 min. spaces apart from the hour hand. To be coincident, it must gain 15 min. spaces. 55 min. are gained in 60 min. Then 15 min spaces are gained in = 6055├Ч15 min. Therefore, The hands are coincident at 16411 min. past 3 o'clock.
