Answer : 3. "9"
Explanation :
Answer: C) 9 Explanation: The given expression can be simplified as 6 ÷ 2 (1 + 2) The expression can be simplified further by the order of operations, using BODMAS rule. First evaluate Parentheses/Brackets, then evaluate Exponents/Orders, then evaluate Multiplication-Division, and finally evaluate Addition-Subtraction. Now, the expression becomes 6 ÷ 2 (3) According to the order of operations, division and multiplication have the same precedence, so the correct order is to evaluate from left to right. First take 6 and divide it by 2, and then multiply by 3. 6 ÷ 2 × 3 = 3 × 3 = 9 But not 6÷2×3 = 6 ÷ 6 = 1 Hence, 6 ÷ 2 (1 + 2) = 9.

Answer : 2. "Sun"
Explanation :
Answer: B) Sun Explanation: The water cycle is a term for the movement of water between the Earth's surface, the sky and underground. Water evaporates due to heat from the sun. Hence, the water cycle is driven primarily by the energy from the sun. This solar energy drives the cycle by evaporating water from the oceans, lakes, rivers, and even the soil. Other water moves from plants to the atmosphere through the process of transpiration.

Answer : 3. "48/5 days"
Explanation :
Answer: C) 48/5 days Explanation: Amount of work K can do in 1 day = 1/16 Amount of work L can do in 1 day = 1/12 Amount of work K, L and M can together do in 1 day = 1/4 Amount of work M can do in 1 day = 1/4 - (1/16 + 1/12) = 3/16 – 1/12 = 5/48 => Hence M can do the job on 48/5 days = 9 (3/5) days
