व्याख्या :

1. Answer (c) Each time we order 1, one apple is added to the basket but each time when 4 is ordered, one apple is removed from it. Required number of apples = number of 1's - number of 4's = 6 - 4 = 2 2. Answer (d) Each time we order 1, 2 or 3, one fruit is added to the basket but when ever we order 4, two fruits are removed from it. Required number = Number of 1's + Number of 2's + Number of 3's - 2 x (Number of 4's) = 6 + 6 + 7 - (2x4) = 19 - 8 = 11.

उत्तर : 3. "528"
व्याख्या :

Answer: C) 528 Explanation: Assume x soldiers join the fort. 1200 soldiers have provision for 1200 (days for which provisions last them)(rate of consumption of each soldier)= (1200)(30)(3) kg. Also provisions available for (1200 + x) soldiers is (1200 + x)(25)(2.5) k As the same provisions are available=> (1200)(30)(3) = (1200 + x)(25)(2.5) x = ([(1200)(30)(3)] / (25)(2.5)) - 1200 => x = 528.

उत्तर : 2. "9801"
व्याख्या :

Answer: B) 9801 Explanation: Clearly, alternatively we add and subtract 10% of a term to obtain the next term of the series.Thus, 10000 + (10% of 10000)= 11000; 11000 - (10% of 11000) = 9900; 9900 + (10% of 9900)  = 10890; 10890 - (10% of 10890) = 9801. 9801 + (10% of 9801)  = 9801+980 = 10781.So, missing term = 10890- (10% of 10890)= 9801.
