Answer: Option D

Explanation:

Let the initial length and width be L and W respectively.

Initial area = L×W

New length = 2L

New width = 2W

New area = 2L×2W = 4 L×W

Increase in area = (4 L×W - L×W) / (L×W) × 100% = 300%

Answer: Option D

Explanation:

Let, length and width of the rectangle are a and b respectively.
initial area = ab
Now rectangle’s length and breath are both doubled,
New length =2a
New width =2b
so, Area of new rectangle = (2a) × (2b) = 4ab
Increase in Area = 4ab - ab = 3ab
therefore,Percentage increase in area = 3ab/ab × 100 = 300 %

Answer: Option C

Explanation:

Hints: উভয় ক্ষেত্রেই train টি একই দূরত্ব অতিক্রম করে। তখন বেগ kmph এ দেওয়া কিন্তু সময় দেওয়া মিনিটে। এই kmph এর মানকে 60 দ্বারা ভাগ করে মিনিটে নিতে হবে।

ধরি, original time t.

প্রথম ক্ষেত্রে দূরুত্ব = বেগ × সময় = 40 /60 (t + 11)

দ্বিতীয় ক্ষেত্রে, দুরুত্ব = 50/60 (a + 5)

এখন, 40/60(t + 11) = 50/60 (t + 5)

t = 19 minutes
