• # question_answer 12) Two numbers are in ratio 3 : 4. 15% of larger number added to 53 becomes equal to 25% of smaller plus 29. The smaller number is A)  440                             B)  640           C)  680                             D)  480

(d): Let nos. be 3x and 4x. According to statement, $\frac{15}{100}\times 4x+53=\frac{25}{100}\times 3x+29$ $\Rightarrow 53-29=\frac{15}{100}x$. $\Rightarrow 24=\frac{15}{100}x$ $\Rightarrow \frac{\cancel{24}\times 100}{\cancel{15}}=160$ $3x=480.$
