Numbers from 8 to 92 were written on paper slips (one number on one slip) and were kept in a box. Then, a slip was taken out from the box, without looking into it. What is the probability that the number on the slip will be a multiple of 7 ?
कागज़ की पर्चियों पर 8 से 92 तक की संख्याएँ लिखी गईं (प्रत्येक पर्ची पर एक संख्या) तथा उन्हें एक डिब्बे में रख दिया गया । फिर, इस डिब्बे में से, बिना संख्या देखे, एक पर्ची निकाली गई । इस पर्ची पर 7 का गुणज एक संख्या प्राप्त होने की क्या प्रायिकता है ?

Correct answer: (A) 12/8512/85

Explanation

There are 92 - 8 + 1 = 85 slips. Multiples of 7 in this range are 14, 21, ..., 91, i.e. 7 × 2 to 7 × 13, which is 12 numbers. Probability = 12/85.पर्चियाँ कुल 92 - 8 + 1 = 85 हैं। इस सीमा में 7 के गुणज 14, 21, ..., 91 हैं, यानी 7 × 2 से 7 × 13 तक, कुल 12 संख्याएँ। प्रायिकता = 12/85।
