Answer 1

Step-by-step explanation:

${\huge{\boxed{\tt{\color {red}{Answer❀✿°᭄}}}}}$

let's take all X

2x:3x:4x

2x = 6

X = 3

so length of pencil b is 3 × 3= 9

length of pencil c is = 5 × 3 = 15

Answer 2

Answer:

Let take ratios be 2x, 3x, 5x.

length of A = 2x = 6cm

2x = 6

x= 6/2

x = 3

A = 2x3 = 6cm

B = 3x3 = 9cm

C = 5x3 = 15cm

total A,B,C = 30cm
