Answer: D) 18.75 % Explanation: Given,S.I = 3 Principal Amount=> 3A = A x 16 x R/100By solving, we get => R = 18.75%

Answer: D) 700 Explanation: Let number of boys = B Number of girls = G From the given data, 1B/3 + 1G/2 = 300 But given B/3 = 100 => B = 300 G/2 = 300 - 100 G = 200 x 2 => G = 400 Therefore, total number of students in the college = B + G = 700.

Answer: C) 3 Explanation: Given   1.21x0.91.1x0.11   = 1.21x100x0.9x101.1x10x0.11x100   = 9   = 3.

STARTLING is a required 9 letter English word is still a word each time you remove a letter from the word. And how it is shown below:    1. Remove the L, and the word becomes: STARTING 2. Remove one T, and the word becomes: STARING 3. Remove the A, and the word becomes: STRING 4. Remove the R, and the word becomes: STING 5. Remove the other T, and the word becomes: SING 6. Remove the G, and the word becomes: SIN 7. Remove the S, and the word becomes: IN 8. Remove the N, and the word becomes: I

Answer: B) 1024 Explanation: Fruits reduced by 1/4.Total no. of bags N = 5Formula to find no. of fruits in 1st bag = 4^nLast Bag = 4 fruits.That means, 4th bag = 4 x 4 = 16 fruits3rd bag = 16 x 4 = 64 fruits2nd bag = 64 x 4 = 256 fruits1st bag = 256 x 4= 1024 fruits.

Answer: D) 156 Explanation: Here the given series 7  18  42  94  204 follows a pattern that,  7 7 ×2+4 = 18 18 ×2+6 = 42 42 ×2+10 = 94 94 ×2+16 = 204 Similarly, 4 4 ×2+4 = 12 12 ×2+6 = 30 30 ×2+10 = 70 70 ×2+16 = 156 Hence, the value of P = 156.

This can be solved in two ways using only 6, 11, 9 and 3 we must get 24. 1. {[(11–6) x 3] + 9} By solving this we get 5 x 3 + 9 = 15 + 9 = 24.   2. [(9–6) x (11–3)] = 3 x 8 = 24.
