  • question_answer 25) The temperature dropped 15 degree Celsius in the last 30 days. If the rate of temperature drop remains the same, how many degrees will the temperature drop in the next 10 days?


                    Given, in last 30 days, temperature drop = 15 degree \[\therefore \] In 1 day, temperature drop \[=\frac{15}{30}\]degree \[=\frac{15\div 15}{30\div 15}=\frac{1}{2}\]degree [\[\because \]HCF of 15 and 30 = 15] \[\therefore \] In next 10 days, temperature drop \[=\frac{1}{2}\times 10\] degree = 5 degree Hence, temperature dropped 5 degree in the next 10 days.
