Question

a का वेतन b के वेतन से 30% अधिक है , b का वेतन के वेतन का 40% है! A , b और c
तीनों का कुल वेतन 7680 रुपए है तो a का वेतन होगा​

Answer 1

Step-by-step explanation:

Let the salary of C be ₹ x.

Therefore,

B's salary = 40% of C's salary

= 0.4x

A's salary =B's salary+30% of B's salary

$\therefore A's \:salary=0.4x + 0.3 \times 0.4x \\ =0.4x + 0.12x \\ = 0.52x \\ \because \: (A's + B's + C's) \: salary \: = 7680 \\ \therefore \: 0.52x + 0.4x + x = 7680 \\ \therefore \: 1.92x = 7680 \\ \therefore \: x = \frac{7680}{1.92} \\ \therefore \: x = \frac{7680}{1.92} \\ \therefore \: x = 4000 \\ now \\ A's\: salary = 0.52x \\ = 0.52 \times 4000 \\ = Rs. \: 2080.$

Hence,

A's salary = ₹ 2080
