Number in the form `15q + 7` can be written as :
(A) `3m + 3` (B) `5m + 2` (C) `5m + 3` (D) `3m + 2`​

Add: 5m - 7n, 3n - 4m + 2, 2m - 3mm - 5

If m=2 find the value of : (i) m-2 (ii) 3m-5 (iii) 9-5m (iv) 3m^2-2m-7

A B C is such that A B=3c m , B C=2c m and C A=2. 5 c m . If D E F A B C and E F=4c m , then perimeter of D E F is 7. 5 c m (b) 15 c m (c) 22. 5 c m (d) 30 c m .

If 3m = 5m - 8/5 , then m = ?

Which of the following pairs of triangles are congruent? If they are congruent, write out the pairs of equal angles. A B C : A B=3c m , B C=4c m , C A=2 c m D E F : D E=2 c m , E F=3 c m a n d F D=4 c m P Q R : P Q=17 c m , Q R=15 c m , P R=18 c m D E F : D E=18 c m , E F=17 c m , D F=15 c m .

If m: n = 3:7 , then (6m – 2n) : (5m + 3n) is equal to

If a 1.5 m tall girl stands at a distance of 3 m from a lamp-post and casts a shadow of length of 4.5 m on the ground, then the height of the lamp-post is (a) 1.5 m (b) 2 m (c) 2.5 m (d) 2.8 m

(b) Find the value of m, if x +2 is a factor of x^(3) -4x^(2) + 3x - 5m
