Question : The distance between the centres of two circles of radii 6 cm and 3 cm is 15 cm. The length of the transverse common tangent to the circles is:
Option 1: $12\ \text{cm}$
Option 2: $6\sqrt6\ \text{cm}$
Option 3: $7\sqrt6\ \text{cm}$
Option 4: $18\ \text{cm}$
Correct Answer: $12\ \text{cm}$
Solution : Given: The distance between the centres of two circles of radii 6 cm and 3 cm is 15 cm. The length of the transverse common tangent to the circles, $= \sqrt{d^2-(r_1+r_2)^2}$ $= \sqrt{15^2-(6+3)^2}$ $= \sqrt{225-81}$ $= \sqrt{144}$ $= 12\ \text{cm}$ Hence, the correct answer
Question : Directions: LOQR is related to GJLM in a certain way based on the English alphabetical order. In the same way, SVXY is related to NQST. To which of the following is NQST related, following the same logic?
Option 1: INMO
Option 2: IMOQ
Option 3: ILNO
Option 4: IMNO
Correct Answer: ILNO
Solution : Given: LOQR is related to GJLM and SVXY is related to NQST.
Subtract 5 from the place value of LOQR to obtain the required code – L – 5 = G; O – 5 = J; Q – 5 = L; R – 5 =
