low temperature at the night in a city is 1/3 more than 1/2 hinge as h...
let x be the highest temp. then,
x+x/2+x/6=100.
therefore, x=60 which is the highest temp
and 100-x=40 which is the lowest temp.

Given,
- Low temperature at night = (1/2) x Higher temperature in a day + (1/3) x (1/2) x Higher temperature in a day
- Sum of low temperature and highest temperature = 100C
To find: Low temperature
Let's assume the higher temperature in a day as 'x'
Then,
Low temperature at night = (1/2)x + (1/3) x (1/2) x x
= (1/2)x + (1/6)x
= (2/3)x
Sum of low and high temperature = Low temperature + Higher temperature = (2/3)x + x = (5/3)x
Given, sum of low and high temperature = 100C
Therefore, (5/3)x = 100C
=> x = (3/5) x 100C
=> x = 60C
Now, substituting the value of x in the equation for low temperature at night, we get
Low temperature at night = (2/3) x 60C
= 40C
Hence, the correct option is A) 40C.
