1.	In the given figure, there are two circles with centers A and B. The common tangent to the circles touches them, respectively,at P and Q. AR is 40cm and AB is divided by the point of contact of the circles in the ratio `5:3` What is the ratio of the length of AB to that of BR ?A. `1:4`B. `2:3`C. `2:5`D. `7:4`
Answer» Correct Answer - 2 `(r_(1))/(r_(2))=(5)/(3)=(AR)/(BR)` or `BR=(3 xx 40)/(5) =25 ` cm `(AB)/(BR)=(40-24)/(24)=(16)/(24)=(2)/(3)`
