1. In 1998, a county suffered from drought and only received 201.6 tons of grain, 40% less than the previous year. How many tons of grain was collected in the previous year? 201.6 △ 1-40% = 336 (tons) 2. Two baskets of eggs were originally 35, and then five of them were taken out of basket a and put into basket B. at this time, the number of basket B was 4 / 3 of that of basket a? (35 + 5) △ 35-5) = 4 / 3

Question 1: there is a batch of milk candy on the supermarket shelf. After two fifths of it is sold, 16 packets are added. At this time, the number of milk candy packets on the shelf is just four packets less than the original 80%. How many there are? Question 2: there is a batch of goods, one fourth of it is transported away for the first time, and 21 tons are transported away for the second time. At this time, the ratio of the remaining tons to the transported ones is 2:3. How many tons are there originally

1. Suppose that the original x package: (1-2 / 5) x + 16 = 80% x-4 x = 100 answer: the original 100 package 2. Suppose that the original y ton: (1-1 / 4) y-21 = 2 / 3 (1 / 4Y + 21) y = 60 answer: the original 60 ton

2、7 ÷（1—20%—18%）
1/4 x+40%x=12

（1） 2.7÷(1—20%—18%）
=2.7÷（80%—18%）
=2.7 △ 82% (i.e. 0.82)
=29268292682. (≈ 3.29 or 329.2%)
（2）1/4 x+40%x=12
0.4x=12-0.25
0.4x=11.75
x=11.75÷0.4
x=29.375
