The half life of a radioactive isotope ' \( \mathrm{X} \) ' is 20 years. It decays to another element ' \( \mathrm{Y} \) ' which is stable. The two elements ' \( \mathrm{X} \) ' and ' \( \mathrm{Y} \) ' were found to be in the ratio of \( 1: 7 \) in a sample of a the given rock. The age of the rock is estimated to be (a) 60 years (b) 80 years (c) 100 years (d) 40 years 📲PW App Link - https://bit.ly/YTAI_PWAP 🌐PW Website - https://www.pw.live
