Answer:
(1) 3 apples
(2) 12 noon - 2.00 PM
(3) 9 P 9 L 9 Q 9 M 9 = -71.
Step-by-step explanation:
(1)
⇒ Given, 2 apples = 4 cherries.
Then, 1 apple = 2 cherries. ----- (i)
⇒ Given, 1 apple + 3 cherries = 2 cherry's + 1 grape
2 cherries + 3 cherries = 2 cherries + 1 grape
5 cherries = 2 cherries + 1 grape
3 cherries = 1 grape ---- (ii)
Hence, from (ii),
1 grape = 3 cherries
Then, 2 grapes = 6 cherries
That means 2 grapes = 3 apples {from (i)}.
Therefore, 2 grapes = 3 apples.

(2)
Total number of members working in an office = 20.
⇒ First five people work between 8 AM and 2.00 PM.
⇒ Second ten works between 10.00 AM and 4.00 PM.
⇒ Third five works between 12.00 AM and 6.00 PM.
The three groups work simultaneously during 12.00 PM to 2.00 PM.
Therefore, Computer are likely to be used most at 12.00 PM to 2.00 PM

(3)
A. 32 P 8 L 16 Q 4 = 32 + 8 ÷ 16 - 4
= 28.5
B. 6 M 18 Q 26 L 13 P 7 = 6 * 18 - 26 ÷ 13 + 7
= 113.
C. 11 M 34 L 17 Q 8 L 3 = 11 * 34 ÷ 17 - 8 ÷ 3
= 19.33
D. 9 P 9 L 9 Q 9 M 9 = 9 + 9 ÷ 9 - 9 * 9
= 9 + 1 - 81
= -71.
Therefore, the answer is 9 P 9 L 9 Q 9 M 9 = -71.
Hope it helps!
