Answer 21.
Volume of water in conical vessel $=\frac { 1 }{ 3 } \times \frac { 22 }{ 7 } \times 25\times 24{ cm }^{ 3 }$
Let h be the height to which the water will rise in the cylindrical vessel
Volume of conical vessel = Volume of cylindrical vessel
$\therefore \quad \quad \quad \frac { 1 }{ 3 } \times \frac { 22 }{ 7 } \times 25\times 24=\frac { 22 }{ 7 } \times 10\times 10\times h$ => h=2cm

Steps of Construction:
CBSE Sample Papers for Class 10 Maths Paper 6 42
Step I: Draw BC = 5 cm.
Step II: With B as centre and radius BA = 7 cm, draw an arc.
Step III: With C as centre and radius CA = 6 cm, draw another arc, intersecting the arc drawn in step 2 at A.
Step IV: Join AB and AC to obtain ∆ABC.
Step V: Below BC, make an acute angle ∠CBX.
Step VI: Mark seven points as B₁ B₂, B₃, B₄, B₅, B₆ and B₇ on BX, such that BB₁ = B₁B₂ and so on.
Step VII: Join B₅ to C and draw line through B₇ parallel to B₅C intersecting the extended line segment BC at C.
Draw a line through C’ parallel to CA intersecting the extended line segment BA at A’.
Thus, ∆A’BC’ is the required triangle.
