7)c
8)a
9)a
10)e

Solution 7: 98,182,266 all are divisible by 14
So ans 14 litres (you take HCF also)

Solution 8: C.P=x ,M.P=45,S.P=42
(42-x)/x=0.05
x=40

Solution 9: A cools at 40min other at 45min together = (45*40)/85 = 21.1764 = about 22 min

Solution 10: 12 candles for 12 had a loss of rs 2.40
So C.P ia 14.40 for 12 candles
Now 16 for 12
So 16-14.40= 1.60
Had a gain of rs 1.60

8)Given M.P=45,S.P=42, Profit = 0.05

Let C.P=x , Then

Profit = (42-x)/x = 0.05
=> x = 40.

7. ANS : c) 14L
Largest measuring cylinder means HCF . Find HCF of the 3 capacities
HCF of 98,182,266 = 14

8.ANS : a) Rs 40
Price of the pack = 42
x*105/100=42 . 105=100(Price of soap pack) + 5(profit)
x=42*100/105=2*100/5=40

9. a) 22 min
Take LCM of 40 and 45 = 360
40*9=360 / 45*8=360.
So if both are switched on together , room cooled in 360/(8+9)=360/17=21.16 minutes
21.16 can be round to 22 minutes , so about 22 minutes

10.ANS : e) gains 1.6
12 candles = 12 rupees . Lose = 2.4
So actual cost = 12+2.4=14.4 rupees .
So if he sells for 16 rupees then he gains 16-14.4=1.6 rupees!

9)Let the two conditioners be A and B

'A' cools at 40min

'B' at 45min

Together =(axb)/(a+b) = (45x40)/85 = 21.1764 = (approx) 22 min.

8)let us take s.p=42
profit% is=5
then (42/100)*5==2.1
then 42-2.1=39.9(approx==40)
