CBSE Class 10 Maths Most Repeated Questions with Answers

Q1. A standard deck of 52 playing cards has had the King, Queen, and Jack of clubs removed, leaving 49 cards. After shuffling the remaining cards, calculate the probability of drawing a specific card from these remaining cards.

(i) Probability of drawing a card of spades:
There are 13 spades in a full deck. Since the King, Queen, and Jack of clubs are removed, the total number of cards is now 49.
Probability = 13/49

​(ii) Probability of drawing a black king:
There are 2 black kings (King of Spades and King of Clubs). However, since the King of Clubs is removed, only the King of Spades remains.
Probability = 1/49

​(iii) Probability of drawing a card of clubs:
After removing the King, Queen, and Jack of Clubs, there are 10 clubs left in total.
Probability = 10/49

​(iv) Probability of drawing a jack:
Since only the Jack of Clubs was removed, there are still 3 jacks remaining (Jack of Hearts, Jack of Diamonds, and Jack of Spades).
Probability = 3/49

Q2. In triangle ΔABC, let altitude AD intersect CE at point P. Prove the following:

(i) Prove ΔAPD ~ ΔCPD:
Since AD and CE are altitudes meeting at P, angles APD and CPD are equal (both right angles), and angle PAD is equal to angle PCD (alternate interior angles). Therefore, by AA similarity criterion:
ΔAPD ~ ΔCPD

(ii) Prove AP × PD = CP × PE:
PD​⟹AP×PE=CP×PD

From the similarity ΔAPD ~ ΔCPD:CP

(iii) Prove ΔADB ~ ΔCEB:
By AA similarity (angles ADB and CEB are equal as they correspond to vertical angles), we have:
ΔADB ~ ΔCEB(iv) Prove AB × CE = BC × AD:
From the similarity ΔADB ~ ΔCEB:BCAB​=CEAD​⟹AB×CE=BC×AD

Q3. A solid consists of a cone placed on top of a hemisphere, both with a radius of r=3.5 cm and a total height of h=9.5 cm.

AP​PEPD​⟹AP×PE=CP×

Q5. Finding Missing Frequency Values Given that the median is 525 for the dataset with total frequency N = 100:

Q6. Two people start walking towards each other from a distance of 16km. If they meet in 2hours:
Let speeds be v1​ and v2​.

Then,v1​+v2​=16km/2hour = 8 Km/hr

If they walk in the same direction:

They meet after 8hours:

v1​−v2​=16km/8hour​=2km/hr

Now solving these two equations:

v1​+v2​=8km/hr

v1​−v2​=2km/hr

Adding these gives:

2v1​=10km/hr→v1​=5km/hr

Substituting back gives: v2​=8−v1​=3km/hr

Thus speeds are:

Person A: 5 km/hr

Person B: 3 km/hr

Q7. If the sides AB, BC, and median AD of triangle ABC are proportional to the corresponding sides PQ, QR, and median PM of triangle PQR, prove that triangle ABC is similar to triangle PQR.

Q8. Two individuals are located 16 km apart on a straight path. They start walking at the same time, and if they walk toward each other at different speeds, they meet in 2 hours. However, if they walk in the same direction at their respective speeds, they meet after 8 hours. Find the walking speeds of both individuals.

Q9. Given that -4 is a root of the quadratic equation $x^2 + 2x + 4p = 0$$x$$2$$+$$2$$x$$+$$4$$p$$=$$0$, determine the value of $k$$k$ for which the quadratic equation $x^2 + px(1 + 3k) + 7(3 + 2k) = 0$$x$$2$$+$$px$$($$1$$+$$3$$k$$)$$+$$7$$($$3$$+$$2$$k$$)$$=$$0$ has equal roots.

Q10. Prove that: (1 + cot A+ tan A) (sin A - cos A) = sec³ A-cosec³ A / sec² A. cosec² A (CBSE 2011-2020)
