Answer 1

Answer:

i. 23:7

ii. 7:23

iii. 7:16

iv. 23:30

Step-by-step explanation:

Nirmal's age= 69 years

Purnima's age= 21 years

Difference of their ages= 69-21 =48

Sum of their ages= 69+21 = 90

i. Nirmal's age : Purnima age

                    69:21                   (divided by 3)

                    23:7

ii. Purnima's age : Nirmal's age

                         21:69              (divided by 3)

                          7:23

iii. Purnima's age : Difference of their ages

                         21:48              (divided by 3)

                          7:16

iv. Nirmal's age : Sum of their ages

                       69:90                (divided by 3)          

                       23:30
