Ques. 9 - Raj can row a certain distance downstream in 12 hr and can retern the same distance in 18 hr. If the stream flows at the rate of 6 km/hr, find the speed of Raj in still water.

राज अनुप्रवाह में एक निश्चित दूरी को तैरने में 12 घंटे और उसी दूरी से वापस आने में 18 घंटे लगाता है। यदि प्रवाह की दर 6 किमी/ घंटा हो, तो राज की शांत जल में चाल क्या है?


(A) 15 kmph/ किमी/घंटा

(B) 20 kmph/ किमी/घंटा

(C) 25 kmph/ किमी/घंटा

(D) 30 kmph/ किमी/घंटा

Sol. (D) – Let the speed of Raj in still water be x kmph/माना राज की स्थिर जल में चाल x किमी/घं. है |
                 speed in downstream/अनुप्रवाह चाल = (x + 6)
                 and speed in upstream/और ऊर्ध्वप्रवाह चाल = (x - 6)
                 12(x + 6) = 18(x - 6)
                 2x + 12 = 3x - 18
                 x = 30 kmph/ किमी/घं.

Ques. 10 - A train overtakes two persons walking along a railway track. The first one walks at 4.5 kmph and the other one walks at 5.4 km/hr. The train needs 8.4 sec and 8.5 sec. respectively to overtake them. What is the speed of the train if both the person are walking in the same direction as the train?

एक रेलगाड़ी दो व्यक्ति जो रेलवे पथ के अनुदिश चल रहे हैं, को पार करती है। पहला 4.5 किमी/घंटा और दूसरा 5.4 किमी/घंटा की चाल से चल रहा है। रेलगाड़ी द्वारा उनको पार करने में लगा समय क्रमशः 8.4 सेकण्ड और 8.5 सेकण्ड हैं। रेलगाड़ी की चाल क्या है, यदि व्यक्ति रेलगाड़ी की ही दिशा में चल रहे हैं?

(A) 66 kmph/ किमी/घंटा

(B) 72 kmph/ किमी/घंटा

(C) 78 kmph/ किमी/घंटा

(D) 81 kmph/ किमी/घंटा

Sol. (D) – 

Speed of first man/पहले आदमी की चाल = SSC Quiz : Quantitative Aptitude | 03 - 02 - 18= 1.25 m/sec (मी./से.)
and speed of second man/और दूसरे आदमी की चाल = SSC Quiz : Quantitative Aptitude | 03 - 02 - 18= 1.5 m/sec (मी./से.)
Let the speed of the train be x km/hr./माना ट्रेन की चाल x किमी./घंटा है |
According to the question/प्रश्नानुसार,
(x – 1.25) × 8.4 = (x – 1.5) × 8.5
8.4x – 10.5 = 8.5x – 12.75
0.1x = 2.25
x = 22.5
Speed in km/hr./किमी./घंटा की चाल = 22.5 × SSC Quiz : Quantitative Aptitude | 03 - 02 - 18= 81 km/hr./किमी./घंटा
