Just figured it out, so M gonna answer my own question. The side of the tile will be the HCF of the length and breadth s = HCF ( L & B ) HCF of 2.47 & 2.09 is 0.19 Total Area = 2.47 * 2.09 Area of tile = 0.19 * 0.19 Number of tiles = Total Area / Area of tile = 143 Hence B P.S. These seems f...

Mitch, From a strict formula point of few. n(A U B U C) = n(A) + n(B) + n(C) - n(A N B) -n(B N C) - n(C N A) + n(A N B N C) or T = N + C + S - (NC + NS + SC) - 2(NCS) The definition of n(A) in the sets formula and the definition of 'N' which you are using differs in way that n(A) includes only A and...

Your picked numbers are NOT fitting into the below criteria
Besides I think picking number's is a long and convoluted solution to this problem.The median of set S is (3/4)b. The median of set Q is (7/8)c.

IMO C . Since all sets contain consecutive integers, we can conclude that its an EVENLY spaced set where median = mean. For S , median = a+b/2 = b*3/4 which results simplifies b = 2a For Q , median = c+b/2 = b*7/8 which results simplifies 4b = 3c Combining the above two, we can arrive 8a = 3c Now Se...

IMO E . The question is vague as it does not explicitly mention whether r is the internal radius or the external. Assuming that r is external radius. Radius of empty hole space = r-t Area of Ring will be Area of full circle - Area of empty hole π r^2 - π (r-t)^2 which simplifies to π t(2r-t) Henc...

Clearly "in addition.." is a modifier here and it should describe or modify the noun after the comma. But here it implies that protein is having more protein than wheat does. this is wrong. It is the rice which has more protein than wheat does. so we need to have rice in the start of the ...

IMO A The term can be summarized as 7^d*3 + 2(a) where d denotes days and a denotes age. From the above term we can state that the first term will always be odd and the second even even + odd = odd Since all numbers of the set will be odd The median of 14th and 15th term = (odd + odd)/2 since odd + ...

From the question, we can clearly infer that this is a Geometric Progression such as below. 5 , 5x , 5x^2 , 5x^3.... The nth term of a G.P. is = a* r ^(n-1) Since y is the number of new members after 12 weeks, y = 5 * x ^ (12-1) = 5 * x ^ 11 On checking our answers, A,B,C,E can be eliminated straigh...

The approach would be to Identify a perfect square closest to the 2 points. Between 15 & 200 15 would have the P.S. 16 closest to it (4^2). Try one number below it - 3 , hence 3*4 = 12. which is out of the range. 4*5 = 20 which is the next consecutive set of consecutive numbers in the range. Hen...

The G.P. described (a,b,c,d) can be written as a , ar , ar^2 , ar^3 where r is the constant ratio which is multiplied. 1. dk, ck, bk, ak becomes ak , akr , akr^2 , akr^3 which is still a G.P. Hence True 2. a+k, b+2k, c+3k, d+4k The above form is an Arithmetic Progression and cannot be expressed in t...
