If ₹2,239 is divided among 269
If ₹2,239 is divided among 269 children such that each girl and each boy get ₹7 and ₹9, respectively, then how many boys are there?
यदि ₹2,239 को 269 बच्चों में इस प्रकार विभाजित किया जाता है कि प्रत्येक लड़की और प्रत्येक लड़के को क्रमशः ₹7 और ₹9 प्राप्त होते हैं, तो लड़कों की संख्या ज्ञात कीजिए।
Detailed Solution & Logic
Correct Answer:
178
Let the number of boys be $x$.
Then number of girls = $269 - x$.
Step 1: Form the equation
Each boy gets ₹9 and each girl gets ₹7.
Total money distributed = ₹2239.
$ 9x + 7(269 - x) = 2239 $
Step 2: Simplify
$ 9x + 1883 - 7x = 2239 $
$ 2x + 1883 = 2239 $
$ 2x = 2239 - 1883 $
$ 2x = 356 $
$ x = 178 $
