A householder spent his monthly salary of ₹7,200 on different items. If he spent ₹4,000 on food and ₹400 on education, then the central angles respectively are:
Answer & explanation
Correct answer: option 1
Rs. 7200 = 360 ̊
Re 1 = \(\frac{360 ̊}{7200}\) = \(\frac{1}{20}\)
⇒ Central angle on food = \(\frac{1}{20}\) x 4000 = 200 ̊
⇒ Central angle on education = \(\frac{1}{20}\) x 400 = 20 ̊
