Step-by-step explanation:
A.
1.) P = R x B
P = 5% x 30
P = 1.5
2.) P = R x B
P = 1% x 60
P = 6
3.) P = R x B
P = 20% x 10
P = 2
4.) P = R x B
P = 6% x 56
P = 3.36
5.) P = R x B
P = 15% x 80
P = 12
B.
1.) Let x be the no. of students who are absent in the class
Rate = 80%
Base = 45
P = ?
P = R x B
P = 80% x 45
P = 36 ( no. of present in the class)
X = B - P
X = 45 - 36
X = 9 ---> the no. of absent students
2.) Let x be the no. of mangoes
X = R x B
X = 64% x 25
X = 16
let y be the no. of avocadoes
Y = R x B
Y = 16% x 25
Y = 4
3.) let x be the no. of boys
let y be the no. of girls
X = 55% x 40
X = 22
y = B - X
y = 40 - 22
y = 18
4.) let x be the no. of planned activities successfully implemented
X = 85% x 20
X = 17
5.) 23.15% x 35 = 8.1025
ans. 8.10 kg.
