13. (13^-20-a*13^y)=168*13^-22
13^-20 - 168*13^-22 = a * 13^y
13^-22 (13^2 - 168) = a * 13^y
Thus,
a = 13^2 -168 = 169 - 168 = 1.
y = -22 (substitute powers of 13)
Therefore, a=1, y=-22.

11 A)Given:
CP of 12 clips is 60
SP of 12 clips = (1+20/100)*60
=(120/100)*60
= 72
HENCE SP OF 12 CLIPS=72
THEN SP of 1 clip= 72/12 = 6 ( this is SP OF ONE CLIP with 20% profit)
Now if he sells 10 clips SP WILL BE 60 ie)) 6*10
HENCE ANS is d

11) Vendor has to spend 72/- for each clip (by considering 20% of 60 rs). For 12 clips he spent 720(60rs*12),
now the vendor has to spend 72/- such that he has to spent total of 720/- then he has to buy
10 clips to satisfy the equation!!

11. d
12.d
from west to 115 (15-10) degrees is north east
13. d
(13^-20-a*13^y)=168*13^-22
by solving this we get 1= a(13^(y+22))
hence by opt verification a=1 and y= -22

11 . ANS=5
12 clips bought for 60 rupees
No of clips that must be sold for 60 rupees to get 20% profit = ?
120% of x =60 . x = 100*60/120 = 50
No of clips that must be sold = 50/(price of 1 clip) = 50/5=10

12. ANS=North-East
N
W E
S
Clockwise degree - Anti-clockwise degree 115%
90% of W = N
115-90=25 degree . 25 degree of N will lie between N and E = North-East

13.ANS : d(1,-22)
(13^-20-a*13^y)=168*13^-22
Divide the LHS and RHS by 13^-22
13^2-a*13^(y+22) =168
168 can be expressed as 13^2 - 1
13^2-a*13^(y+22) =13^2 - 1
a*13^(y+22) =1
Now look at options and substitute .. Its easy for y=-22 . 13^0=1 a also = 1
So option d

11) 12 -> 60
1 -> 5
SP = 60
Profit = 20%
Sp = p% of Cp
60 = 120/ 100 *x
x= 50
So , the number of clips he should sell is 50/5 = 10

Sujitha S  (8 years ago)

Totally we have 12 clips...So (x÷12)×100=20...now x=6...so for each 6 means 72 rs(i.e 6×12=72)...but in ques they asked for 60rs..So the Ans is 10 clips(i.e 10×6=60)
