Answer : 2. "8%"
Explanation :
Answer: B) 8% Explanation: Let the shopkeeper buy 300g for Rs.300. Now he sells 100g for Rs.110, another 100g for Rs120, and the rest 100g for Rs94. Therefore, the total amount he receives = Rs.110 + Rs.120 + Rs.94 = 324. Therefore, the shopkeeper spends Rs.300 and gets back Rs.324. Therefore, his profit percentage = 24300x100 % = 8%

Answer : 1. "TRUE"
Explanation :
Answer: A) TRUE Explanation: Yes, a square is a rhombus. But a rhombus is not a square unless the interior angles are at right angles. We know that, a square is a quadrilateral with all sides equal and all the interior angles are 90 deg i.e, at right angles. Whereas a rhombus is also a quadrilateral with all sides equal but the interior angles are not at right angles. Hence, if the interior angles of a rhombus are all at right angles (90 deg), then it is square.
