Question

the product of 2- digit numbers is 2925 . if the product of their units digits is 45 and that of their tens digits is 21 . find the numbers ​

Answer 1

Answer:

here it is given that unit place is multiplied and we get 45

therefore by multiplying 9 *5 we get 45

now multiplying tens digit we get 21

therefore we have 3*7=21

now trying all possible values we get the answer which is one of them

trying 39*75we get 2925

Step-by-step explanation:

let the two numbers be "ab" and "xy"

so it is given that b*y =45 and a*x = 21

ab*xy = 2925

45 = 1*3*3*5 and 21 = 1*3*7

so there are 4 chances b=9, y=5 , a=3, x=7

                                      b=9,y=5, a=7, x=3

                                       b=5, y= 9, a=3,x= 7

                                       b=5,y=9, a=7, x=3

now check all of them you will get the answer
