Question
P, Q, R, S and T are five friends standing in a straight
line facing towards north. P is on the immediate right of Q. T is between P and S. If R and Q are at the ends, which of the following is second to the left of R?Solution
(i) If R and Q are at the ends of the row, then there will be two cases: Case 1: Case 2:
(ii) P is on the immediate right of Q. T is between P and S. Now here Case 1 will not follow. Hence, Case 2 will be the final arrangement:

What will come in the place of question mark (?) in the given expression?
(β676 of β144 Γ· 13) of 2400% = ?Β
(47.5 ÷ 9.5) × (78.5 ÷ 15.7) + 475 = ? + 15% of 150
20% of (β9216 + ?) = 24
20 × 224 ÷ 16 – 50 = ? + 100
...144 (1/2) Γ 14 β 28 = 7 Γ ?Β
- What will come in place of the question mark (?) in the following questions?
75%Β ofΒ 240 + 30 = ? Simplify: 3/4 + {5/6 Γ· (2/3 β 1/6)} β 7/8
- What will come in place of (?) in the given expression.
(β of 450) β (β of 300) = ? 1555.5 + 1000.8 – 1354.3 = ? + 52
116 ÷ 280 of 1/2 + 3/5 × 5/3 = ?
