Solutions

S1. Ans.(d)
Sol. ‘Throttle’ controls the flow of ‘fuel’ to the engine.
Similarly, ‘Faucet’ controls the flow of ‘Water’.

S2. Ans.(d)
Sol. ‘Bass’ is a larger version of ‘Violin’.
Similarly, ‘Saxophone’ is a larger version of ‘flute’.
‘Flute’ and ‘Saxophone’ are wind musical instruments.


S5. Ans.(b)
Sol. The given expression is 40 ÷ 360 × 24 – 4 + 18
Using the symbols correctly as given in the above question, the above expression becomes
40 + 360 ÷ 24 × 4 – 18
Using BODMAS RULE, we get
40 + 15 × 4 – 18 = 40 + 60 – 18
= 100 – 18 = 82
Therefore, the value of the given expression = 82


S7. Ans.(b)
Sol. Present age of Manick = 12 years.
Then present age of Rahul = 4 years. (given)
After x years, Manick’s age = 12 + x
After x years, Rahul’s age = 4 + x
According to the question
(12 + x) = 2 (4 + x)
Or, 12 + x = 8 + 2x
Or, x = 4
Therefore, Required age of Manick = (12 + x) years
= (12 + 4) years
= 16 years

S8. Ans.(d)
Sol. My father’s age was x in the year x²
By hit & trial method, x = 44 as 44² = 1936.
∵ The square of any other integer will not fall in between 1900 and 2000.
So, my father was 44 in the year 1936
Therefore, my father was born in the year = (1936 – 44) = 1892
