- Explanation : (B) Lecture Method is not suitable to teach lower classes. Because in the lower classes the students are in the lower age and they do not have so developed mind that could understand the oral lecture.
63. If P:Q = 5:8, Q:R = 12:7 and R:S = 14:15, then the value of P:S will be
- Option : A
- Explanation : (A) P: Q = 5: 8 Q: R = 12: 7 R:S=14:15 P: S =? P:Q:R=5 x12:8 x12:8 x7 =60:96:56 =15:24:14 P: Q:R:S = 15 :24:14:15 Hence, P:S=15:15 =1:1
