In a certain pattern, if 38 * 15 = 32, 62 * 91 = 7 and 74 * 81 = 29, then in the same pattern the value of 47 * 33 is :यदि किसी निश्चित पैटर्न में 38 * 15 = 32, 62 * 91 = 7 तथा 74 * 81 = 29 हो, तो उसी पैटर्न में 47 * 33 का मान है :

Correct answer: B. 41
Explanation
Reverse the digits of both numbers and subtract the second from the first: 83 − 51 = 32, 26 − 19 = 7 and 47 − 18 = 29, which match all three given results. For 47 * 33 this gives 74 − 33 = 41.दोनों संख्याओं के अंक उलटकर पहले में से दूसरा घटाइए : 83 − 51 = 32, 26 − 19 = 7 तथा 47 − 18 = 29 — तीनों दिए गए परिणाम मिल जाते हैं। इसी नियम से 47 * 33 का मान 74 − 33 = 41 होगा।More Reasoning & Mental Ability questions
