(C) 25%
(D) 21%
Answer Key:
Q1. (B) Let M.P. be Rs.x/माना अंकित मूल्य x रु. है ।
S.P./विक्रय मूल्य = Rs./रु.1920
Discount/छूट % = 4%
4x = 100x – 192000
96x = 192000
x = Rs./रु.2000
Q2. (C) Single discount/एकलछूट =
= (55 – 9.5 + 0.5)
= 46%
Q3. (D) S.P.1 – S.P.2 = 10
x = 15%
y = 10%
C.P. = Rs.200
Q4. (B) (sec A + tan A – 1) [sec A – (tan A – 1)] = sec2A – (tan A – 1)2
= sec2A – tan2A – 1 + 2 tan A
= 1 + tan2A – tan2A – 1 + 2 tan A
= 2 tan A
Q5. (A) Ratio of profit/लाभ में अनुपात =
= 3: 2
If/यदि A = 300
then/तो B = 200
A's investment/A का निवेश = 300 × 4 + 150 × 8
B's investment/B का निवेश = 12 × 200 = 2400
Since investment is same. So/चूंकि निवेश समान है । अतः,
A's profit/A का लाभ = = Rs.250
Q6. (C) Tuesday/मंगलवार + Wednesday/बुधवार + Thursday/गुरुवार = 37 × 3 = 111
Friday/शुक्रवार + Wednesday/बुधवार + Thursday/गुरुवार = 38 × 3 = 114
Temperature of Friday/शुक्रवार का तापमान = 39
39 – Tuesday/मंगलवार = 3
Tuesday/मंगलवार = 39 – 3 = 360C
Q7. (B) Total milk/कुल दूध =
Total water/कुल पानी =
Ratio of new mixture/नए मिश्रण का अनुपात = = 83: 22
Q8. (D) 100 × d1 = (100 + 100) × 5
100 × d1 = 1000
= 10 days/दिन
40 – 35 = 5 days/दिन
10 – 5 = 5 days after the scheduled time/निर्धारित समय से 5 दिन बाद
Q9. (A) Let x and y be the cost price of the two watches.
माना दोनों घड़ियों के क्रय मूल्य x और y हैं ।
x + y = 1350
6% of z/z का 6% = % of y/y का %
x = = Rs./रु.750
Q10. (C) If the C.P. be Rs.100/यदि क्रय मूल्य 100 रु. है ।
S.P./विक्रय मूल्य = 115
S.P./विक्रय मूल्य = 92% of marked price/अंकित मूल्य का 92%
92% of marked price/अंकित मूल्य का 92% = Rs./रु.115
Marked price/अंकित मूल्य = = Rs./रु.125
Required/अभीष्ट % = 25%
