25 % of 120 + 40% of 380 = ? of 637 (a) 2/7 (b) 1/7 (c) 4/7 (d) 3/7
If 60% of A = 30% of B, B=40% of C and C = x % of A, then value of x is (a) 800 (b) 200 (c) 300 (d) 500

If 30% of A = 0.25 of B =1/5 of C, then A:B:C is equal to
If 30% of A = 0.25 of B =1/5 of C, then A:B:C is equal to: (a) 5:6:4 (b) 5:24:5 (c) 6:5:4 (d) 10:12:15 SOLUTION 1: Simplify the equation 30/100 of A = 0.25 of B = 1/5 of C 3/10 * A = 25/100*B = 1/5*C A/(10/3) =B/4 = C/5 Multiply the denominator by 3 A/10=B/12=C/15 A:B:C= 10:12:15 Option (d) CLICK HERE FORE VIDEO SOLUTION
If 50% of (P-Q) = 30 % of (P + Q) and Q = x% of P, then the value of x is (a) 30(b) 25 %(c) 20% (d) 50 %
