**Question 1.Find a range of the following data:19, 27, 15, 21, 33, 45, 7, 12, 20, 26Solution:**

Here, largest value (L) = 45, smallest value (S) = 7

∴ Range = L – S = 45 – 7 = 38

**Question 2.Find range of the following data:575, 609, 335, 280, 729, 544, 852, 427, 967, 250Solution:**

Here, largest value (L) = 967, smallest value (S) = 250

∴ Range = L – S = 967 – 250 = 717

**Question 3.The following data gives a number of typing mistakes done by Radha during a week. Find the range of the data.**

Solution:

Here, largest value (L) = 21, smallest value (S) = 10

∴ Range = L – S = 21 – 10 = 11

**Question 4.The following results were obtained by rolling a die 25 times. Find the range of the data.Solution:**

Here, largest value (L) = 6, smallest value (S) = 1

∴ Range = L – S = 6 – 1 = 5

**Question 5.Find range for the following data:Solution:**

Here, upper limit of the highest class (L) = 72

lower limit of the lowest class (S) = 62

∴ Range = L – S = 72 – 62 = 10
