Assuming ALL were $10 notes, 10 x 92 = 920 920 - 608 = 312 10 - 2 = 8 312 ÷ 8 = 39 ($2 notes) Checking: 39 x $2 + 53 x $10 = $608

Fig 1 = 1 square (1 x 1) Fig 2 = 4 squares (2 x 2) Fig 3 = 9 squares (3 x 3) (a) Therefore Fig 5 = 5 x 5 = 25 squares (b) if this is a P5 qn, kids may have learnt square root. So square root of 169 is 13 (Fig 13). If P4 kids, they need to know ( ) x ( ) = 169, ie 13 (Fig 13) (c) fig 1 - 1 shaded Fig 2 - 2 shaded Fig 3 - 3 shaded.... Up to fig 99 - 99 shaded... Sum = 1 + 2 + 3.......+99 Easy way to add such qn: 99 x 100 ÷ 2 = 4950
