Question

. What is the cost of tiling a rectangular plot of land 400 m long and 150 m wide at the rate of Rs. 6 per metre. *

Answer 1

Step-by-step explanation:

Difference between S.I. and C.I. on Rs.5000 at 4% p.a. for 3 years is 42.32

We know :-

$\sf \bullet \: \: Simple \: interest = \dfrac{p \times r \times t}{100}$

Where,

p(principal) = Rs.5,000

r(rate) = 4% p.a.

t(time) = 3 years.

$\sf = \dfrac{prt}{100}$

$= \dfrac{50 \cancel{00}\times 4 \times 3}{1 \cancel{00} }$

$= 50 \times 4 \times 3$

$= 600$
