   Remaining height
   

   =		192 -	125	% of 192
   			100

   
   = 192 – 120 = 72 m
   ∴ Required distance (distance covered in second hour) then,
   

   =	25	% of 72
   	2

   
   

   =	25 × 72	= 9 m
   	2 × 100

   Water in 100 kg fresh fruit = 68%
   Water in dry fruit = 20%
   Decrease = 48%
   ∴ Dry fruit obtained
   = 100 – 48 = 52 kg.

   Correct Option: C

   Water in 100 kg fresh fruit = 68%
   Water in dry fruit = 20%
   Decrease = 48%
   ∴ Dry fruit obtained
   = 100 – 48 = 52 kg.

   Let z have x
   

   ∴ Money with Y =	3	x and
   	2

   
   Money with X = 3x
   

   ∴ 3x +	3x	+ x = 3 × 110
   	2

   
   

   ⇒	6x + 3x + 2x	= 330
   	2

   
   ⇒ 11 x = 2 × 330
   

   ⇒ x =	2 × 330	= 60
   	11

   
   ∴ Money with
   X = 3x = ₹(3×60) = ₹ 180

   Correct Option: D

   Let z have x
   

   ∴ Money with Y =	3	x and
   	2

   
   Money with X = 3x
