(D) Rs. / रु.1260
Answer Key:
Q1. (C) Let the cost price be Rs.100/माना क्रय मूल्य 100 रु. है |
Gain/लाभ % = 40%
Selling price/विक्रय मूल्य = Rs./रु.140
Let the marked price be Rs.x/माना अंकित मूल्य रु.x है |
Selling price/विक्रय मूल्य = x - 
140 = 
x = 175
Required percentage/अभीष्ट प्रतिशतता = 
= 75%
= 75%
Q2. (B) Let John's present age be x years/ माना जॉन की वर्तमान आयु x वर्ष है।
(x – 7) (x + (B) = 52
x2+ 2x – 7x – 14 = 52
x2– 5x – 66 = 0
x2 – 11x + 6x – 66 = 0
x = 11, x = – 6
Q3. (B) (2277 ÷ 23) + (1950 ÷ 26) – (1053 ÷ 13) = ?
99 + 75 – 81 = ?
? = 93
Q4. (A) Average height of all the students/सभी छात्रों की औसत ऊँचाई
= 
= 
= 115 cm. /सेमी.
= 115 cm. /सेमी.
Q5. (C) C.P. of 1 orange/1 सन्तरे का क्रय मूल्य = Rs./रु.
S.P. of 1 orange/1 सन्तरे का विक्रय मूल्य = Rs./रु.
= Rs./रु.2
= Rs./रु.2
Profit/लाभ % = 
= 
= 20%
= 20%
Q6. (B) Cost Price for A/ A के लिए क्रय मूल्य = Rs./रु. 23.94 × 
= Rs./रु. 24
Q7. (D) Total distance/कुल दूरी = 
= 35 + 
= 
= 35 + =
Required average speed/अभीष्ट औसत चाल = 
= 
=
= 50 km/hr./(किमी./घंटा)
Q8. (C) Let the two numbers be x and x + 1.
माना दो संख्याएं x और x + 1 हैं |
According to the question/प्रश्नानुसार,
x(x + 1) = 9506
x2 + x – 9506 = 0
x2 + 98x 97x – 9506 = 0
x(x + 98) – 97(x + 98) = 0
(x + 98)(x – 97) = 0
x = – 98, 97
Average of the two numbers/संख्याओं का औसत = 
= 97.5
= 97.5
Q9. (A) Old ratio/पुराना अनुपात = 1: 3) × 2 = 2: 6
New ratio/नया अनुपात = 1: 2) × 3 = 3: 6
Difference/अनुपात = 1
1 = 15
New mixture/नया अनुपात = 9 × 15 = 135 liters/ लीटर
Q10. (D) Req. amount of compound interest/अभीष्ट चक्रवृद्धि ब्याज की धनराशि
= 
– 6000
– 6000
= 
– 6000
– 6000
= 7260 – 6000 = Rs. / रु.1260
