Height of five people A, B, C, D, E are given as follows:
A - 165 cm, B - 1.8 m, C - 72 inches, D - 5.9 feet, E - 2.1 yards
Arrange A, B, C, D, E in ascending order.
(1 yard = 3 feet, 1 feet = 12 inches, 1 inch = 2.54cm)

• A. A, D, B, C, E
• B. A, D, C, B, E
• C. A, D, E, C, B
• D. A, D, E, B, C

Answer 1

The correct option is A A, D, B, C, E

We know $1$ m = $100$ cm

$1$ yard = $3$ feet = $3$ x $12$ inches = $36$ inches = $36$ x $2.54$ cm = $91.44$ cm

$1$ feet = 12 inches = 12 x 2.54 cm = $30.48$ cm

Height of A = $165$ cm
Height of B = 1.8 m = 1.8 x 100 cm = $180$ cm
Height of C = $72$ inch = $72$ x $2.54$ cm = $182.88$ cm
Height of D = $5.9$ feet = $5.9$ x 30.48 cm
= 179.832 cm
Height of E = $2.1$ yard = 2.1 x 91.44 cm = 192.024 cm

Height of A, B, C, D, E in cm are $165,180,182.88,179.832,192.024$
So, ascending order: A, D, B, C, E
