Arithmetic • Mixture and Alligation

₹80 प्रति किलोग्राम और ₹160 प्रति किलोग्राम मूल्य वाले दो मसालों को मिलाया जाता है। मिश्रण को ₹140 प्रति किलोग्राम में बेचने पर 25% लाभ होता है। मिश्रण में दोनों मसालों का अनुपात क्या है? Two spices priced at ₹80 per kg and ₹160 per kg are blended. They are sold at ₹140 per kg at a profit of 25%. What is the ratio of the two spices in the mixture?

A. 3 : 2 3 : 2 B. 2 : 1 2 : 1 C. 1 : 2 1 : 2 D. 3 : 1 3 : 1

सही उत्तर: A Correct Answer: A

मिश्रण का क्रय मूल्य = ₹140/1.25 = ₹112 प्रति किलोग्राम। मिश्रण नियम के अनुसार सस्ते और महँगे मसाले का अनुपात = (160 − 112) : (112 − 80) = 48 : 32 = 3 : 2।

The cost price of the mixture is ₹140/1.25 = ₹112 per kg. By alligation, the ratio of the cheaper spice to the dearer spice is (160 − 112) : (112 − 80) = 3 : 2.

Arithmetic • Time and Work

X किसी कार्य को 12 दिनों में और Y उसी कार्य को 18 दिनों में पूरा कर सकता है। यदि दोनों मिलकर 3 दिनों तक काम करें, तो कार्य का कितना भाग शेष रहेगा? X can complete a task in 12 days, while Y can complete it in 18 days. If they work together for 3 days, what fraction of the work will remain?

A. 1/3 1/3 B. 5/12 5/12 C. 7/12 7/12 D. 9/12 9/12

सही उत्तर: C Correct Answer: C

दोनों की एक दिन की कार्यक्षमता = 1/12 + 1/18 = 5/36। तीन दिनों में किया गया कार्य = 15/36 = 5/12। अतः शेष कार्य = 1 − 5/12 = 7/12।

Their combined one-day work is 1/12 + 1/18 = 5/36. In three days they complete 5/12 of the work, leaving 1 − 5/12 = 7/12.

Arithmetic • Pipes and Cisterns

तीन पंप A, B और C किसी जलाशय को क्रमशः 5 घंटे, 7 घंटे और 10 घंटे में भर सकते हैं। तीनों पंपों को एक साथ खोला जाता है और वे 1.5 घंटे तक चलते हैं। इसके बाद पंप C बंद कर दिया जाता है। शेष जलाशय को भरने में कितना अतिरिक्त समय लगेगा? Three pumps A, B and C can fill a reservoir in 5 hours, 7 hours and 10 hours respectively. All three operate together for 1.5 hours before pump C is closed. How much additional time will be required to fill the reservoir?

A. 1/2 घंटा 1/2 hour B. 43/25 घंटे 43/25 hours C. 47/48 घंटा 47/48 hour D. 45/41 घंटे 45/41 hours

सही उत्तर: C Correct Answer: C

तीनों की संयुक्त दर = 1/5 + 1/7 + 1/10 = 31/70। 1.5 घंटे में भरा भाग = 31/70 × 3/2 = 93/140। शेष भाग = 47/140। A और B की संयुक्त दर = 1/5 + 1/7 = 12/35। आवश्यक समय = 47/140 ÷ 12/35 = 47/48 घंटा।

The combined rate of all three pumps is 31/70. In 1.5 hours they fill 93/140, leaving 47/140. The combined rate of A and B is 12/35, so the additional time is 47/140 ÷ 12/35 = 47/48 hour.
