text Interest =â¹(6325-5500) 825=(5500 × 6 × r/100) ⇒ r=(825 × 100/5500 × 6)=2.5 % Interest when ROI is doubled is 825 × 2 = â¹ 1650 Interest when time is half =(825/2)= text Rs. 412.50

Q. ₹ 5500 becomes ₹ 6325 at certain rate of simple interest in a period of 6 years. On the basis of information given below, choose the correct pair.

Column - I Column - II

I Rate of interest P 5%

II Time reduce to half Q ROI doubled

III Interest doubles R 2.5%

S Time increase to 12 years

$I - Q; III - S$

$I - P; II - S$

$II - R; III - P$

$I - R; III - Q$

$Interest = ₹ (6325 - 5500)$
$825 = \frac{5500 \times 6 \times r}{100}$
$\Rightarrow r = \frac{825 \times 100}{5500 \times 6} = 2.5%$
Interest when $RO I$ is doubled is $825 \times 2$ $= ₹1650$
Interest when time is half
$= \frac{825}{2} = Rs. 412.50$

Column - I		Column - II
I	Rate of interest	P	5%
II	Time reduce to half	Q	ROI doubled
III	Interest doubles	R	2.5%
		S	Time increase to 12 years
