Answer: 80
Explanation Number of tiles on one side of the room = 21 tiles. Total tiles = B21×4= 84 . Since 4 tiles at each corner are shared by both rows, subtract these: 84−4= 80 tiles.
Answer: 32
Explanation 2 × 2 = 4 4 × 2 = 8 8 × 2 = 16 16 × 2 = 32
Answer: 96162
Explanation Assigning numerical values based on a pattern: B = 5, E = 6, A = 4, T = 2 → BEAT = 5642 S = 6, W = 6, E = 9, E = 1, T = 2 → SWEET = 66912 T = 9, E = 6, A = 1, S = 6, E = 2 → TEASE = 96162 .
Answer: 100
Explanation 15% of 201 = 30.15 13937.869/199.54= 69.85 finally 30.15+69.85 which is equal to 100 .

Answer: 22.86 days
Explanation Step 1: Find total work in man-days 80 men complete the bridge in 20 days. Total work = 80 × 20 = 1600 man-days Step 2: Find time for 70 men Time = Total work / Number of men = 1600/ 70 Time = 22.86 days
Answer: 36.5
Explanation Correct sum = (36 * 50 + 48 – 23) = 1825. Correct mean = 1825/50 = 36.5
Answer: 5%
Explanation P 1 = Rs.800 P 2 = Rs.400 Time = 2 years Difference in S.I. = Rs.40 Formula used: S.I. = (PRT)/100 Calculation: (P 1 RT)/100 – (P 2 RT)/100 = 40 ⇒ RT(800 – 400) = 4000 ⇒ R = 4000/800 ⇒ R = 5% ∴ The rate of simple interest is 5% .
Answer: 180 degrees
Explanation The angle sum of a triangle will always be equal to 180°. The angle sum of a quadrilateral is equal to 360° And a triangle can be created by slicing a quadrilateral in half from corner to corner. Since a triangle is essentially half of a quadrilateral Its angle measures should be half as well. Half of 360° is 180°
Answer: 40
Explanation Let there be x pupils in the class. Total increase in marks = (x * 1/2) = x/2 x/2 = (83 – 63) => x/2 = 20 => x = 40
