CTET Solved Paper - UTET April 2015
- A
the pupil will be able to distinguish between features of a cylinder and a cone
- B
the pupil will be able to draw the figure of a cylinder and a cone
- C
the pupil will be able to recall the formulae for calculating volume and surface area of cylinder and cone
- D
the pupil will be able to find the height of a cone when a given cylinder is melted into cone
- Option : A
- Explanation : The pupil will be able to distinguish between features of a cylinder and a cone.
- Option : D
- Explanation : Let the number of coins of
each type be x
2x/3 x 50/100 + (3x/4) x l = 26
⇒x/3 + 3x/4 = 26
⇒ 4x+9x=26 × I2
⇒ 13x = 26 × 12 ⇒ x = 24
145. In the following figure, the value of x is 
- Option : B
- Explanation : ∠CBA =180° -65°=115°.
∠DCB =180° -80°=100°.
∠EDC=1I5°.
∠A =90°.
∠DEA =540°.
- (115°+ 100° + 115° + 90°) =120°.
[sum of all angles 'in a pentagon is
540°].
∠x = 180° -120°=60°
