Answer: A) 225 deg Explanation: Angle of triangle = 180 × 3/12 = 45 deg Other angles of the triangle are = 60 deg, 75 deg Angle of quadrilateral = 360 - (45 + 60 + 75) = 180 deg Therefore, the four angles of the quadrilateral are 45, 60, 75 & 180 degrees. Hence, the sum of largest and smallest angle of the quadrilateral are 180 + 45 = 225 deg.

A Hole. When you are digging a hole the more you take out the soil, the igger the hole becomes.

We know that polar substances are soluble in polar solvents and non polar substances are soluble in non-polar solvents only. Here the hydrocarbons are non-polar molecular substances and water is a polar solvent. So water can't dissolve hydrocabons.   Hence, as hydrocarbons are non-polar substances, they are insoluble in water as it is a highly polar solvent.

Answer: A) 20 Explanation: Let the total amount be 200 {L.C.M of 40 and 50} Chacobar C.P. = 200/50 = 4 Fivestar C.P = 200/40 = 5 Remaining Money after petrol = [200 - 200×10%] = 180 Remaining money after buying fivestars = [180 - 20×5] = 80 So number of Chacobar she can buy = 80/4 = 20

Energy tranfer takes place either by means of Heat or Work only in Thermodynamics. Heat :: Heat Energy is defined as Energy that can be transferred due to temperature change. Whereas Thermal Energy :: Thermal Energy is the Internal Energy stored in the system maintained at a certain Temperature.

While eating a watermelon, we all go along the red and stops at green.

Answer: A) Rs. 704 Explanation: We know that, S.I. = PTR100⇒ P = S.I x 100T x RAnd also,C.I = P1 + R100n- 1 From given data, P = Rs. 8625 Now, C.I  = 86251+41002-1= 862526252-1= 8625676625-1= 8625 x 51625C.I = Rs. 703.80
