Question : Find the distance (in cm) between the centres of two circles having radii of 32 cm and 24 cm, respectively if the length of a direct common tangent to the two circles is given as 24 cm.
Option 1: 60
Option 2: 65
Option 3: 64
Option 4: 63
Correct Answer: 64
Solution : Direct common tangent to two circles = $\sqrt{d^{2}-(r_{1}-r_{2})^{2}}$ Let $r_{1}$ and $r_{2}$ be 32 cm and 24 cm respectively. Length of a direct common tangent to the two circles, $d = 24 \sqrt{7}$ cm Direct common tangent to two circles = $\sqrt{d^{2}-(r_{1}-r_{2})^{2}}$ ⇒ $24 \sqrt{7}
Question : A man travels 400 km partly by train and partly by steamer. He spends 9 hours more time on the steamer. If the velocity of the steamer is 30 km/hr and the velocity of the train is 70 km/hr, how much distance does he cover by steamer?
Option 1: 309 km
Option 2: 371 km
Option 3: 464 km
Option 4: 556 km
Correct Answer: 309 km
Solution : Let $D$ denote the distance (in km) that the man covers by steamer. According to the question, $\frac{D}{30}-9=\frac{400-D}{70}$ $⇒\frac{D}{30}-9=\frac{40}{7}-\frac{D}{70}$ $⇒\frac{D}{21}=\frac{103}{7}$ $\therefore D= 309$ km Hence, the correct answer is 309 km.
