Consider the following tributaries of River Yamuna and arrange them from West to East : 1. Betwa 2. Ken 3. Sindh 4. Chambal Select the correct answer from the codes given below. Codes :
- (a)4, 3, 1 and 2
- (b)1, 2, 3 and 4
- (c)3, 2, 1 and 4
- (d)2, 3, 1 and 4
Correct — A, 4, 3, 1 and 2. The Yamuna's main right-bank tributaries rise on the Malwa Plateau / Bundelkhand and join it in sequence from west to east: Chambal (4) is the westernmost, joining near Etawah; then Sindh (3); then Betwa (1), joining at Hamirpur; and Ken (2) is the easternmost, joining near Chilla (Banda). So west-to-east reads Chambal, Sindh, Betwa, Ken = 4, 3, 1, 2, which is option (a).
- (b)1, 2, 3 and 4 — Betwa, Ken, Sindh, Chambal — this neither runs west-to-east nor east-to-west correctly; Chambal (westernmost) cannot be last.
- (c)3, 2, 1 and 4 — Sindh, Ken, Betwa, Chambal — jumbled; Ken is the easternmost and cannot come second, and Chambal cannot be last.
- (d)2, 3, 1 and 4 — Ken, Sindh, Betwa, Chambal — this is essentially east-to-west (reversed) and misplaces Ken at the start.
The Yamuna is the largest tributary of the Ganga, meeting it at Prayagraj (Triveni Sangam). Along its middle course it collects several right-bank tributaries draining the Vindhyan uplands and Bundelkhand — Chambal, Sindh, Betwa and Ken. Their confluences lie progressively eastward: Chambal (westernmost) → Sindh → Betwa → Ken (easternmost).
This is a spatial-ordering question. The reliable memory hook is the confluence longitude: Chambal joins around Etawah (west), Betwa at Hamirpur, and Ken near Banda (east). Fixing just the two ends — Chambal westmost, Ken eastmost — eliminates every option except (a).
- Yamuna is the largest tributary of the Ganga; it joins the Ganga at Prayagraj
- Main right-bank tributaries, west to east: Chambal, Sindh, Betwa, Ken
- Chambal (via Etawah) is westernmost and is itself the Yamuna's biggest tributary; Ken (near Banda) is easternmost
- Betwa joins the Yamuna at Hamirpur; all four rise on the Malwa Plateau / Bundelkhand
West-to-east order = Chambal, Sindh, Betwa, Ken = 4, 3, 1, 2 → answer (a).
- Reversing the order to east-to-west (a common option-d style trap)
- Forgetting that Chambal is a right-bank tributary of the Yamuna (not of the Narmada)
Rivers are asked as arrange-in-order (west-east / north-south) or tributary-to-main-river matching — pin the confluence points and the two extremes to crack the sequence.
Consider the following pairs: Tributary River – Main River 1. Chambal : Narmada 2. Sone : Yamuna 3. Manas : Brahmaputra Which of the pairs given above is/are correctly matched?
- (a) 1, 2 and 3
- (b) 1 and 2 only
- (c) 2 and 3 only
- (d) 3 only
Answer(d) 3 only — Chambal joins the Yamuna (not the Narmada) and the Son joins the Ganga (not the Yamuna); only Manas-Brahmaputra is correct.
Tests the same Yamuna-tributary knowledge — UPSC's answer confirms Chambal is a tributary of the Yamuna, the westernmost of the four this question orders geographically.
Which of the following statement is correct? (1) Ram Ganga river joins the Ganga at Kannauj. (2) River Betwa joins the Yamuna near Prayagraj. Select the correct answer using the code given below –
- (a) Only 2
- (b) Both 1 and 2
- (c) Neither 1 nor 2
- (d) Only 1
Answer(d) Only 1
UPPSC's own 2023 paper tests Betwa as a right-bank tributary of the Yamuna and its confluence point — exactly the Yamuna-tributary geography ordered here.
Which one of the following (Tributary – River) is not correctly matched?
- (a) Manjra – Godavari
- (b) Hemavathi – Kaveri
- (c) Pranhita – Mahanadi
- (d) Malaprabha – Krishna
Answer(c) Pranhita – Mahanadi
Same tributary-to-main-river matching skill applied to peninsular rivers — reinforces mapping each tributary to its correct trunk river.

- (b)Ken
- (c)Chambal
- (d)Sindh
Answer(c) Chambal — the westernmost and largest right-bank tributary of the Yamuna.
- practice — not a real PYQ
