Q: If 25% of three-seventh of 26% of a number is 145.5, what is the number? 1434 0

Answer : 3. "5223"
Explanation :
Answer: C) 5223 Explanation: Given, 25% of three-seventh of 26% of a number is 145.5 Let the required number be 'N' i.e, 25100x37x26100xN = 145.5 N = 145.5x7x1000075x26 => N = 5223.07

Q: What will come in place of the question mark (?) in the following question ? 52.5% of 800 + 30.5% of 2800 = ? + 87.30 1430 0

Answer : 4. "1186.70"

Q: Simplify the following equation [K-L2-K+L2]4K = a/b 1427 0

Answer : 2. "bL = -a"
Explanation :
Answer: B) bL = -a Explanation: [(K-L)2-K+L2]4K = abK2+L2-2KL-K2+L2+2KL4K= ab => - 4KL/4K = a/b => L = - a/b => bL = -a

Q: Area of a square and a rectangle are equal. If side of the square is 40 cm and length of the rectangle is 64 cm, what is the perimeter of the rectangle ? 1422 0

Answer : 2. "178 cm"
Explanation :
Answer: B) 178 cm Explanation: Area of square = 40 x 40 = 1600 sq.cm Given that the areas of Square and Rectangle are equal => Area of rectangle = 1600 Sq.cm We know that, Area of rectangle = L x B Given L = 64 cm Breadth of rectangle = 1600/64 = 25 cm Perimeter of the rectangle = 2(L + B) = 2(64+25) = 178 cm.

Q: A Tank is normally filled in 9 hours but takes four hours longer to fill because of a leak in its bottom. If the tank is full, the leak will empty it in ? 1418 0

Answer : 2. "29.25 hrs"

Answer: B) 814 Explanation: Length of largest tile = H.C.F. of 1517 cm and 902 cm = 41 cm.Area of each tile = (41 x 41) sq.cm Required number of tiles =1517 x 902/(41 x 41) = 814.

Q: Find the principal if the interest compounded at the rate of 10% per annum for two years is Rs. 420 ? 1415 0

Answer : 1. "Rs. 2000"
Explanation :
Answer: A) Rs. 2000 Explanation: Given, Compound rate, R = 10% per annumTime = 2 yearsC.I = Rs. 420Let P be the required principal.A = (P+C.I)Amount, A = P1 + r100n (P+C.I) = P1 + 101002 (P+420) = P[11/10][11/10] P-1.21P = -420 0.21P = 420 Hence, P = 420/0.21 = Rs. 2000
