1. What was the ratio of item sold by P on Sunday & items sold by S on Saturday?

A. 3 : 1 B. 11 : 8 C. 2 : 1 D. 9 : 13 E. None of these

Answer: Option C
Explanation: Items sold by P on Sunday = 40 Items sold by S on Saturday = 20 Hence, the required ratio = [latex]\frac{40}{20}[/latex] = 2 : 1
2. Items sold by S on Sunday is what percent of item sold by Q on Tuesday?

Answer: Option B
Explanation: Items sold by S on Sunday = 25 and Items sold by Q on Tuesday = 45 Therefore the reqd. % = [latex]\frac{25}{45}[/latex] × 100% = 55.55%

A. 33 B. 30 C. 28 D. 35 E. None of these

Answer: Option B
Explanation: Items sold by P on Monday = 25 Items sold by Q on Tuesday = 45 Items sold by S on Saturday = 20 Therefore the reqd. average = [latex]\frac{25 + 45 + 20}{3}[/latex] = 30
4. Find the ratio of the sum of items sold by P on Saturday and Tuesday to that of the items sold by S on Saturday and Sunday?

A. 17 : 16 B. 14 : 11 C. 16 : 17 D. 17 : 15 E. None of these

Answer: Option E
Explanation: Sum of items sold by P on Saturday and Tuesday = (45 + 35) = 80 Sum of items sold by S on Saturday and Sunday = (20 + 25) = 45 ⇒ The required ratio = 80 : 45 = 16 : 9
5. P sold certain items on Wednesday which was 60% of the total items sold by S on Monday and Tuesday both. find the items sold by P on Wednesday.

A. 66 B. 35 C. 35 D. 48 E. None of these

Answer: Option D
Explanation: Items sold by S on Monday = 41 Items sold by S on Tuesday = 39 Total items sold by S on Monday and Tuesday = 41 + 39 = 80 Now, items sold by P on Wednesday = 60% of Items sold by S on Monday and Tuesday Therefore, 60% of 80 = 48

Answer: Option C
Explanation: 1454 + 2365 + 9710 + 3020 = ? ⇒ ? = 1454 + 2365 + 9710 + 3020 ⇒ ? = 16549
3. 67.5% of 960 + ?% of 640 = 728

A. 12.5 B. 25 C. 12 D. 11 E. None of these

Answer: Option A
Explanation: 67.5% of 960 + ?% of 640 = 728 [latex]\frac{67.5}{100}[/latex] × 960 + [latex]\frac{?}{100}[/latex] × 640 = 728 648 + ? × [latex]\frac{640}{100}[/latex] = 728 ⇒ ? × [latex]\frac{640}{100}[/latex] = 728 – 648 ⇒ ? × [latex]\frac{640}{100}[/latex]= 80 ⇒ ? = [latex]\frac{80 × 100}{640}[/latex] ⇒ ? = 12.5
4. 19 ÷ [1 – [latex]\frac{1}{2}[/latex] + 2 [latex]\frac{2}{3}[/latex]] = ?

A. [latex]\frac{1}{6}[/latex] B. 6 C. [latex]\frac{1}{2}[/latex] D. [latex]\frac{1}{19}[/latex] E. None of these

Answer: Option B
Explanation: 19 ÷ [1 – [latex]\frac{1}{2}[/latex] + 2 [latex]\frac{2}{3}[/latex]] = ? ⇒ ? = 19 ÷ [1 – [latex]\frac{1}{2}[/latex] + 2 [latex]\frac{2}{3}[/latex]] ⇒ ? = 19 ÷ [3 – [latex]\frac{1}{2}[/latex] + [latex]\frac{2}{3}[/latex]] ⇒ ? = 19 ÷ [3 – [latex]\frac{3}{6}[/latex] + [latex]\frac{4}{6}[/latex]] ⇒ ? = 19 ÷ [3 + [latex]\frac{1}{6}[/latex]] ⇒ ? = 19 ÷ [latex]\frac{19}{6}[/latex] ⇒ ? = 19 × [latex]\frac{6}{19}[/latex] ⇒ ? = 6
5. (√8 × √8)[latex]\frac{1}{2}[/latex] + [latex]\frac{91}{2}[/latex] = [latex]{?}^{3}[/latex] + √8 – 340

A. 7 B. 19 C. 18 D. 9 E. None of these

Answer: Option A
Explanation: (√8 × √8)[latex]\frac{1}{2}[/latex] + [latex]\frac{91}{2}[/latex] = [latex]{?}^{3}[/latex] + √8 – 340 ⇒ (8)[latex]\frac{1}{2}[/latex] + [latex]\frac{91}{2}[/latex] = [latex]{?}^{3}[/latex] + √8 – 340 ⇒ (4 × 2)[latex]\frac{1}{2}[/latex] + [latex]\frac{91}{2}[/latex] = [latex]{?}^{3}[/latex] + √(4 × 2) – 340 ⇒ 2√2 + 3 = [latex]{?}^{3}[/latex] + 2 √2 – 340 ⇒ 3 = [latex]{?}^{3}[/latex] + – 340 ⇒ [latex]{?}^{3}[/latex] = 340 + 3 = 343 ⇒ [latex]{?}^{3}[/latex] = 7
