Solved Example on Oval
Ques: How many ovals will come in the 35th arrangement of the pattern?
Choices:
A. 69
B. 71
C. 68
D. 67
Correct Answer: A
Solution:
Step 1: The rule for the pattern is to start from 1 and count up the number of ovals by 2 for each arrangement.
Step 2: Number of ovals in the nth arrangement = 2n - 1
Step 3: Number of ovals in the 35th arrangement = 2(35) - 1 = 70 - 1 = 69
Step 4: So, 69 ovals will come in the 35th arrangement in the pattern.
Quick Summary
- Oval is derived from the Latin word 'Ovus' meaning egg.
- Only one tangent can be drawn at each point of an oval.
