Answer: C) 26 Explanation: Here the puzzle follows the logic that Right side number = sum of the number on the left side and the previous number on the left side => 6 = 4+2 => 10 = 6+4 => ? = 16+10 = 26.

Answer: A) Y Explanation: If you add all the terms of the LHS of equality, then the last letter of the sum written in words would give you the RHS. 1 + 1 + 1 + 1 = 4 = FOUR 2 + 2 + 2 + 2 = 8 = EIGHT 3 + 3 + 3 + 3 = 12 = TWELVE 4 + 4 + 4 + 4 = 16 = SIXTEEN   So, following the same pattern. 5 + 5 + 5 + 5 = 20 = TWENTY   That gives us our answer to 5 5 5 5 =  "Y".

Answer: A) +6 Explanation: In H2SO4, Hydrogen has a charge of +2, with each hydrogen has +1. Oxygen has  a charge of -8, with each oxugen has -2. Total charge = (2 - 8) = -6 Therefore, the Oxidation number of Sulphur S is '+6' because to make the compound stable.

Answer: A) TRUE Explanation: We know that, Alternate Exterior Angles Theorem:: The Alternate Exterior Angles Theorem states that, when two parallel lines are cut by a transversal, the resulting alternate exterior angles are congruent . Converse of the Alternate Exterior Angles Theorem :: Converse of the Alternate Exterior Angles Theorem states that, If two lines are cut by a transversal and the alternate exterior angles are congruent, then the lines are parallel.

Answer: B) 1/2 Explanation: We know that: When one card is drawn from a pack of 52 cards The numbers of possible outcomes n(s) = 52 We know that there are 26 red cards in the pack of 52 cards⇒ The numbers of favorable outcomes n(E) = 26 Probability of occurrence of an event: P(E)=Number of favorable outcomes/Numeber of possible outcomes=n(E)/n(S) ∴ required probability = 26/52 = 1/2.

Answer: C) 28 hrs Explanation: 1/K + 1/L + 1/M = 1/8 (Given)Also given that K = 2L and L = 2M=> 1/2L + 1/L + 2/L = 1/8=> (1 + 2 + 4)/2L = 1/8=> 2L/7 = 8=> L = 28 hours.

Answer: A) Autotrophs Explanation: Plants make their own food through the process of photosynthesis. Plants are self-sufficient. Green plants have the ability to prepare their own food and this is the reason why they are called autotrophs.                                          They make their own food through the process of photosynthesis using light energy to make sugars from carbon dioxide (C02) and water (H20). The chlorophyll which is present in the leaves is the main reason for the production of food in the plants and it is the reason for the greenery of the leaves too.

Answer: C) Rs. 7000 Explanation: Let the sum be Rs. S.(S x 18 x 2)/100 - (S x 12 x 2)/100 = 840 => 36S/100 - 24S/100 = 840 => 12S/100 = 840 => S = 7000.
