A university library budget committee must reduce exactly five of eight areas of expenditure - I, J, K. L, M, N, O and P - in accordance with the following conditions: If both I and O are reduced, P is also reduced. If L is reduced, neither N nor O is reduced. If M is reduced, J is not reduced. Of the three areas J, K and N exactly two are reduced. If both K and N are reduced, which one of the following is a pair of areas neither of which could be reduced?

A pressure cooker and a rice cooker were originally sold for Rs. 1200 and Rs. 2000 respectively by the Shopkeeper. During a sale, Chaya bought the pressure cooker at 30% discount and the rice cooker at 35% discount. What percentage of the total of the original prices did Chaya save?
A hollow sphere (k = 30 W/m K) of inner radius 6 cm and outside radius 8 cm has a heat generation rate of 4000000 W/m3. The inside surface is insulated and heat is removed by convection over the outside surface by a fluid at 100 degree Celsius with surface conductance 300 W/m2 K. Make calculations for the temperature at the outside surfaces of the sphere
On a winter day with atmospheric air at −15°C, the outside front wind-shield of a car has surface temperature of +2°C, maintained by blowing hot air on the inside surface. If the wind-shield is 0.5 m2 and the outside convection coefficient is 250 W/Km2, find the rate of energy loss through front wind-shield.
Assertion: In a pressure cooker the water is about to be boiled. The cooker is then removed from the stove. Now on removing the lid of the pressure cooker, the water boils again. Reason: The impurities in water bring down its boiling point.
Percy prepares vegetable curry (liquid) in a pressure cooker. If the raw potatoes are P, the raw tomatoes are T, the raw onions are O, and the cooked meal is M, then 2P + T + O → 3M may represent the cooking process. Sometime during the process, Manu opens the lid and checks the curry to find that the potatoes are half-cooked (take XP = 0.5). Volume of the cooker is 5L and CPo = CTo = COo = 1.5. What can you say about the composition in the cooker at the instant of time when the lid is opened, if initial temperature was 310K?
When two fluids of the heat exchanger are separated by a plane wall, the thermal resistance comprises (i) Convection resistance due to the fluid film at the inside surface (ii) Conduction resistance (iii) Convection resistance due to the fluid film at the outside surface Identify the correct option
M, N, O, P, Q, Rand S are sitting around a circular table facing the center and away from the center. O sits second to the left of R, who faces outside. N sits adjacent to M. S is not the neighbor of R. O faces inside. Q is not neighbor of N. M sits third to the right of R and faces outside. The neighbors of M face inside. N is not neighbor of O. The neighbors of R face outside the circle. Who sits second to the right of Q?
