If P means 'greater than (>); Q means 'less than (<)'; R means 'not greater than (≤)'; S means 'not less than (≥) and T means 'equal to (=)', then consider the following statements:

1. If 2x(S)3y and 3x(T)4z, then 9y(P)8z.

2. If x(Q)2y and y(R)z, then x(R)z.

Which of the statements given above is/are correct?

What will come in place of * in the sequence 3, 14, 39, 84, *, 258?

In some code, letters P, Q, R, S, T represent numbers 4, 5, 10, 12, 15. It is not known which letter represents which number. If Q - S = 2S and T = R + S + 3, then what is the value of P + R - T?

Read the following passage and answer the items that follow the passages. Your answers to these items should be based on the passages only.

According to the Food and Agriculture Organization, one-third of food produced for human consumption is lost or wasted globally. Food is lost or wasted throughout the supply chain, from initial agricultural production to final household consumption. The increasing wastage also results in land degradation by about 45%, mainly due to deforestation, unsustainable agricultural practices, and excessive groundwater extraction. The energy spent over wasted food results in about 3-5 billion tonnes of carbon dioxide production every year. Decay also leads to harmful emissions of other gases in the atmosphere. Addressing the loss and wastage of food in all forms is critical to complete the cycle of food sufficiency and food sustainability.

Which of the following statements best reflect the most logical and rational inferences that can be made from the passage?

1. The current methods of food distribution are solely responsible for the loss and wastage of food.

2. Land productivity is adversely affected by the prevailing trend of food loss and wastage.

3. Reduction in the loss and wastage of food results in lesser carbon footprint.

4. Post-harvest technologies to prevent or reduce the loss and wastage of food are not available.
