Here in Fig.I, a 24-hour clock is shown and in Fig.II and Fig.III, sleeping times of two animals X and Y are shown by shaded portions. Select the correct statement about the sleeping times of X and Y:

Here in Fig.I, a 24-hour clock is shown and in Fig.II and Fig.III, sleeping times of two animals X and Y are shown by shaded portions. Select the correct statement about the sleeping times of X and Y: Correct Answer X sleeps for 4 hours while Y sleeps for 18 hours

Explanation:

  • The shaded region of the clock tells about the sleeping hours
  • The clock is divided into 12 parts so each part indicates 2 hours
  • For Animal X, 2 parts are shaded. Thus, it sleeps for 4 hours(2 * 2)
  • For Animal Y, 9 parts are shaded. Thus it sleeps for 18 hours(2 * 9)

Additional Information

  • Animal X sleeps for only 4 hours. This means it is very active and has a high metabolic rate
  • An example of an animal that rests less is an elephant
  •  Animal Y sleeps for 18 hours. This means it is very less active and has a low metabolic rate
  • Such animals are found in areas having extreme climatic conditions

∴ X sleeps for 4 hours while Y sleeps for 18 hours

Equal sized circular regions are shaded in a square sheet of paper of 1 cm side length. Two cases, case M and case N, are considered as shown in the figures below. In the case M, four circles are shaded in the square sheet and in the case N, nine circles are shaded in the square sheet as shown. What is the ratio of the areas of unshaded regions of case M to that of case N?

A 5-stage pipelined processor has Instruction Fetch (IF), Instruction Decode (ID), Operand Fetch (OF), Perform Operation (PO) and Write Operand (WO) stages. The IF, ID, OF and WO stages take 1 clock cycle each for any instruction. The PO stage takes 1 clock cycle for ADD and SUB instructions, 3 clock cycles for MUL instruction, and 6 clock cycles for DIV instruction respectively. Operand forwarding is used in the pipeline. What is the number of clock cycles needed to execute the following sequence of instructions? Instruction Meaning of instruction I0 : MUL R2, R0, R1 R2← R0 * R1 I1 : DIV R5, R3, R4 R5 ← R3 / R4 I2 : ADD R2, R5, R2 R2 ← R5 + R2 I3 : SUB R5, R2, R6 R5 ← R2 – R6
