4(x+2)= 4x + 8.......(1)
3(2x)= 6x..........(2)

Let (1)=(2); since the two perimeters are equal

4x+8=6x
8=2x
X=4

Since x is 4, we sub the value of x into (1) and (2). Becos the question said find the perimeter of the triangle and square.

Therefore the perimeter of the square is 4(4)+8=24
Perimeter of triangle 3(2x4)=24
Q.E.D

bro, check d question well, it ended by saying, FIND X.

Oluwacolded:

maths

1.the length of a side of a square is represented by x+2,and the length of a side of an equilateral triangle by 2x.if the square and the equilateral triangle have equal perimeters find x

a.24
b.16
c.12
d.8


2.which of the following is the smallest

a.(0.11) (0.11)
b.0.00112
c.0.001(1.2)
d.0.00121

3.on a certain day at school,72 students were absent.this represents 9 percent of the enrollment.how many students were enrolled?

A.720
b.800
c.6552
d.80


4. 84.2 is 42.1 percent of

a.42.1
b.50
c.84.2
d.100

SOLUTION

1. 4(x+2)=2x(3)
4x+8=6x
4x-6x=-8
-2x=-8
x=4

2. B

3. (9/100) x X= 72
9x=7200
x=800

4. (42.1/100) x X = 84.2
42.1x=8420
x=200

princesshugo: Naf last year aptitude test: a boy was asked to write the value of (2) rise to power of 5 * (9) rise to power of 2. He wrote it as 2592. The difference between the obtained n d actual value is.

SOLUTION. (Subject to ur correctionz sha o if any dey)

1. (2^5 )x(9^2)= 2592; 2592-2592=0

2. 3hrs 17minz 49secs =(3x60x60)+(17x60)+(49)seconds = 11869secz

1hr 54minz 50secs = (60x60)+(54x60)+(50)seconds = 6890secz
11869-6890=4979secz
@ an interval of 13secz; we hv dat d lite wuld b seen @ 4979/13= 383times

3. Let no of girlz= g and no of boiz= b; g=5b ; total = b+g; this is same as total = b+5b = 6b. there4 the answer shuld b such dat it doesn’t satisfy d condition TOTAL=6b

4. Let y be the correct answer and x the required number.
Then (3/14x)=y………..eqn 1 ;
(3/4x)=150+y…………..eqn2;
Therefore putting eqn 1 in 2 thus
(3/4x)=150+(3/14x); solving for x by collecting like terms and finding lcm gives
x = 8400/30 = 280

5. Let x be the original number and let y bethereqd percentage to get the original number.
20%x + x = 0.2x+x = 1.2x
20%(1.2x)+1.2x= 0.24x+1.2x=1.44x
There4, y%(1.44x)=x
(y/100)=(x/1.44x)
Y=100/1.44= 69.44%
You can verify this using various values of x and see how y brings you back to the initial or original value

6. Let the price of petrol= p, u=% of petrol reqd to maintain former level of consumption in monetary termz
30%p+p=0.3p+p=1.3p= new price
(u/100)x1.3p=p
1.3pu=100p
U=76.92%

7. T=5000,
(10/100male)+(15/100female)=600--------eqn1
Male+female=5000-----------------------------eqn2
Multiplying eqn 1 by 0.15 and solving simultaneously thus:
0.01males+0.15females=600
0.15Male+0.15female=5000x0.15
0.01males+0.15females=600
-0.15Male+0.15female=750
______________________________
-0.05male =-150females
Therefore; males =(150/0.05)=3000males

8. (15/100)x18700=2805 ----loss
Real price =2805+18700=210505
To gain 15%; 15/100 x21505 = 3225.75
3225.75+21505= 24730.75 which is d amount if sold @ 15% gain

9. Friday is 3days b4 Monday. Therefore Wednesday is the answer

10. 9, (9+6)=15, (15+ 8 )=23, (23+10)=33, (33+12)=45

11. 12, (12-8 )=8, (8+6)=14, (14-8 )=6, (6+10)=16, (16-12)=4

12. 68, (68+13)=81, (81+15)=96, (96+17)=113, (113+19)=132

13. 2, (2+3)=5, (5+4)=9, (9+5)=14, (14+6)=20, (20+7)=27

14. Penultimate is the letter before the last. Answer= V[size=8pt][/size]
