Q. A person makes a fixed deposit of Rs. 20000 in Bank of India for 3 years. If the rate of interest be 13% SI per annum charged half yearly. What amount will he get after 42 months? एक व्यक्ति रुपये की सावधि जमा करता है। 20000 बैंक ऑफ इंडिया में 3 साल के लिए। यदि ब्याज की दर 13% SI प्रति वर्ष है, तो अर्धवार्षिक शुल्क लिया जाता है। 42 महीने बाद उसे कितनी राशि मिलेगी?
Q. An amount becomes 8028 in 3 years at a fixed percentage interest rate and 12042 in 6 years, when the interest is compounded annually. What is the actual amount? कोई राशि एक निश्चित प्रतिशत ब्याज दर पर 3 वर्षों में 8,028 रुपये और 6 वर्षों में 12,042 रुपये हो जाती है, जब ब्याज वार्षिक संयोजित है| राशि है?
Given,
Fixed percentage interest rate,
Amount becomes 8028 in 3 years,
$$12042 = P(1+r/100)^6 …(i)$$
$$8028 = P(1+r/100)^3$$
$$8028^2 = P^2(1+r/100)^6 …(ii)$$
Dividing (ii) by (i), we get
$$P = (8028xx8028)/12042 = 5352$$
दिया गया,
निश्चित प्रतिशत ब्याज दर,
3 साल में राशि 8028 हो जाती है,
$$12042 = P(1+r/100)^6 …(i)$$
$$8028 = P(1+r/100)^3$$
$$8028^2 = P^2(1+r/100)^6 …(ii)$$
(ii) को (i) से भाग देने पर हमें प्राप्त होता है,
$$P = (8028xx8028)/12042 = 5352$$
Q. Two-fifth of one-third of three-seventh of a number is 15. What is 40% of that number? एक संख्या के तीन-सातवें के एक-तिहाई का दो-पांचवां हिस्सा 15 है। उस संख्या का 40% क्या है?
Q. The population of of a town is 176000.If it increase at the rate of 5% per annum, what will be it’s population 2 years hence? एक कस्बे की जनसंख्या 176000 है। यदि इसमें 5% वार्षिक की दर से वृद्धि होती है, तो 2 वर्ष बाद इसकी जनसंख्या कितनी होगी?
Q. If 120 is reduced by $$x%$$, the same result will be obtained if 40 is increased by $$x%$$. Then $$x%$$ of 210 will be what percentage less than $$(x + 20)% of 180$$? यदि 120 को $$x%$$ कम किया जाए तो वही परिणाम प्राप्त होगा जो 40 को $$x%$$ बढ़ाने पर प्राप्त होता है | तब 210 का $$x%$$, 180 के $$(x + 20)%$$ से कितने प्रतिशत कम होगा?
$$120(1-x/100)=40(1+x/100)$$
$$3-(3x)/100=1+x/100$$
$$(4x)/100=2$$
$$x=50$$
$$x% of 210 = 210xx50/100=105$$
$$(x+20)% of 180 = 180xx70/100=126$$
Required percentage = $$(126-105)/126 xx 100 = 16 2/3%$$
