The table shows the heights of Noah, Roshel, and Samuel. The average height of three children is 146 cm. The digit in the ones place of Noah's height and the digit in the tens place of Samuel's height are covered by ink blots.
- What is the digit in the ones place of Noah's height?
- What is the digit in the tens place of Samuel's height?
Total height of the three children
= 3 x 146

Total height of Noah and Roshel
= 438 - 148
= 290
290 - 130 - 101
= 59
= 5 tens 9 ones
(a) Digit in the ones place of Noah's height = 9
(b) Digit in the tens place of Samuel's height = 5
