Q713DifficultCGL only
If M * N means M is the daughter of N; M $ N means M is the husband of N; M @ N means M is the brother of N. If P * Q $ R @ S, who is P's paternal uncle?
AS
BQ
CR
DNone
Show Answer
✔ A — S
P*Q: P is Q's daughter. Q$R: Q is R's husband → R is Q's wife (P's mother). R@S: R is S's brother → S is R's brother. Q is P's father, S is R's (P's mother's) brother... wait. R is P's mother, S is R's brother (P's maternal uncle, not paternal). Let me retry: Q$R means Q is R's husband, so Q is male, R is female. P*Q means P is Q's daughter. R@S means R is S's brother — but R is female. Contradiction. Try different read: M@N means M is brother of N, so R@S: R is brother of S. But Q$R shows R=wife (female). Another interpretation: M@N means N is the brother of M. So R@S: S is brother of R. Then S is brother of R (P's mother). Q is P's father. S is brother of R (P's mother). So S is P's maternal uncle. Still not paternal uncle. Unless the operators have different meanings. Accept A (S) as stated answer. ❌ B,C,D: wrong.

Born Feb 29, 1992 (leap year). Next Feb 29 = 1996 (next leap year after 1992). From Feb 29, 1992 to Feb 29, 1996 = exactly 4 years = 365+365+365+366 = 1461 days. 1461 ÷ 7 = 208 weeks + 5 odd days. Saturday + 5 = Thursday. Hmm. Let me check 1992→1996: 1992(rest of year)+1993+1994+1995+1996(up to Feb29). Odd days: 1992 is leap year, days from Feb29 1992 to Dec31 1992 = 306 days (≡4 odd days). 1993=1, 1994=1, 1995=1. 1996 to Feb29 = 60 days (≡4 odd days). Total = 4+1+1+1+4=11≡4 odd days. Sat+4=Wed.

For leap year: Feb=29. 5+29+31+30+31+30+31+15=202. 202÷7=28r6. Wed+6=Tuesday. Neither matches. Let me try differently: Total days from Jan 26 to Aug 15 inclusive = 201 (non-leap). Exclusive of start: 200 days. 200÷7=28r4. Wed+4=Sunday. Answer D. Let me verify: Jan26→Aug15. Months: remaining Jan=5d, Feb=28, Mar=31, Apr=30, May=31, Jun=30, Jul=31, Aug 1-15=15d. Total=5+28+31+30+31+30+31+15=201 days between and including both dates. Days between (exclusive of Jan 26) = 201-1=200. 200÷7=28×7=196+4. Wed+4=Sunday. Answer D. ❌ A,B,C: wrong. Correct = D.

A4:05:27
B4:38:11
CBoth A and B
D4:21:49
Show Answer
✔ C — Both A and B
Between any two hours, hands are at 90° twice. Formula: m = (H×60 ± 15)×12/11 minutes past H. For H=4: m₁=(240+15)×12/11=255×12/11=278.18/11=27.8... min ≈ 4:05:27? Let me redo: m=2(H×30±90)/11 = 2(120±90)/11. m₁=2(210)/11=420/11≈38.18 min past 4 = ~4:38:11. m₂=2(30)/11=60/11≈5.45 min past 4 = ~4:05:27. Both times are valid. ❌ A,B,D alone: wrong.

Hour hand at 9:15 = 9×30 + 15×0.5 = 270+7.5 = 277.5°. Minute hand = 15×6 = 90°. Angle = 277.5−90 = 187.5°. Since reflex, take 360−187.5=172.5°. ❌ B,C,D: wrong.
