Number of digits from 1 to 9 = 9 Number of digits from 10 to 99 = 2 x (99-10+1) = 2 x 90 = 180 Number of digits from 100 to 105 = 3 x (105 - 100 + 1) = 18 Number of digits used = 9 + 180 + 18 = 207

Number of digits from 1 to 9 = 9 Number of digits from 10 to 99 = 180 Number of digits from 100 to 999 = 3 x (999 - 100 + 1) = 2700 Hence, she stopped at a 3-digit number. 843 - 9 - 180 = 654 654/3 = 218 218 + 99 = 317. Hence, she stopped at the number 317.

Cost: 2kg pomelo = 1.5kg durian So, 3kg durian = 4kg pomelo Paid $76.5 for 4.5kg pomelo + 3kg durian Use $76.5 can buy 4.5+4=8.5kg pomelo Cost of 1kg pomelo is $76.5/8.5=$9 Cost of 1kg durian is $9*4/3=$12

Ariel Lim Ah Ping

So x = 180 - y Also from the question, x = 80 + y Equal the 2, u get 180 -y = 80 + y

For primary school students without using algebra or solving simultaneous equations.

I think your model should be reversed since y is an acute angle and x is an obtuse angle.
